Dear Mr. Stübbe,

Thank you for your letter of 24th June to Mary Francis who is away from the office at the moment. I have shown your letter to The Queen who was most interested to read your horseshoe studies. Her Majesty was very grateful to you for taking the trouble to send her the results of your studies and has asked me to send her best wishes to you with this letter.

Yours sincerely

Dear Mr. Henderson

Referring to our talks during our visit to the Royal Mews an the 28th July, I'm sending to you the holographic deformation measurement an a horse's Foot, which makes the tension created by nailing visible.

I wish to take this opportunity to thank you very much for the very kind reception my colleagues and I experienced at the Royal Mews especially for the very interesting and beautiful tour and explanation you gave us of the Mews. Most of all however I have to thank you for the perfect setup you arranged for our shoeing demonstration, beginning with the many interested, encouraging horsemen who gave us the chance to bring up all aspects of the new system and ending with this truly Royal horse.

I'm very much looking forward to our anticipated return to the Royal Mews at the end of this month in order to take off the integrated horseshoes. I will call you in two weeks time to fix the date.

Yours sincerely

Peter Stübbe

Your Majesty

Please allow me to introduce to Your Majesty our nailless horseshoe which adheres to the hoof significantly stronger and longer than today's. Its natural configuration increases the performance and the life expectancy of the horse.

A Methyl Metacrylat paste, which is also used as a cement in hip replacement, is made to harden an the sole and the lower part of the horse's hoof, connecting itself to the hoof horn and binding it, the inserted plastic and steel segments, into an integrated whole.

The enclosed video film and brochure show the shoeing process. The sample of the shoe, which is fabricated onto a transparent hoof model, shows how the loads are evenly distributed over the surface of the foot. When the hoof model is distorted by hand, one can see how well the hoof mechanism is preserved. I have also enclosed an integrated horseshoe that has been in use for two and a half months.

If Your Majesty would be so gracious to grant us the opportunity to shoe one of Your Majesty's horses, and if Your Majesty should approve of the shoe, it would represent a invaluable endorsement of this new thoroughly tested high tech product to the horse community and thus help to relieve the horses of their two thousand year old encumbrance.

Hoping to receive Your Majesty's instructions. I remain Your Majesty's most devoted servant.

Dear Mr. Stübbe,

The Queen has asked me to thank you for your letter of 7th April and for the video, brochure and sample of the nail-less horseshoe which you enclosed.

Her Majesty reviewed all these with considerable interest and was grateful to you for bringing them to her attention. She will certainly bear your invention in mind for the future.

Thank you again for writing.

Yours sincerely

Dear Mrs. Francis

It has been a great honour for me to receive your kind letter dated April 21th 1998 telling me about the interest Her Majesty took in the new shoeing technique. This encouraged me to supply you with two scientific studies. One from the Freie Universitat Berlin concerning the interaction of hoof horn with synthetic horn on a cellular level, made visible by means of a scanning microscope. The other contains pictures of double impulse holograms showing the tension in the hoof wall created by nailing.

Myself, being an admirer of Her Majesty for a long time, have always been motivated by Her Majesties interest in this noble animal, to continue with this twenty five years old development for the horses foot. Our previous shoes, however, have never been marketed at a great scale' because, although being well bonded on the hoof wall, they still had severe disadvantages compared with the classic horseshoe. They needed a bar, or water could rise in small slits for instance. The Integrated Horseshoe abolishes all of these disadvantages and "acts like an outside skeleton to the moving parts of the hoof. z. Since the bonding between the hoof and the synthetic horn is stronger than inside the natural horn masses themselves, no water can get in between and the bonding is also much stronger than that of the classical horseshoe.

I have long planed the day when we could start marketing an a greater scale after the product would be finally ready, and I have promised myself, Her Majesty to be the First horsewomen to know about it. That is why Her Majesty will not meet any other expert who has seen or read about it, except for the people directly involved with its production and research. I wish to express my sincere thanks that I was indeed given the opportunity to do so.

Yours sincerely

Dear Mr. Stübbe,

Mrs. Mary Francis has forwarded your correspondence dated 24th June, 1998 to me to reply to concerning the development of a nail less shoe for horses.

Your research work appears to have been well done and I am sure that theoretically there are many advantages in not using nails. I am however concerned that there appears to be little work done on the type of shoe to be used and the viability of the fixing. In the Royal Mews we have tried various types of different shoes in the past and nothing has survived the London type of work.

However we would be very happy to see a demonstration of the shoe so that if we had a really bad footed horse it would be a useful backup for us.

Yours sincerely

Dear Colonel Gilbart Denham,

Referring to our talks at the Royal Mews an the 25th August I should like to inform you about the state of affairs concerning the improvements of the shoeing procedure and the appearance of the integrated horseshoe you had asked for. We are now in the position to supply you with black artificial horn and we have also come up with an outer mould shell which gives the shoes a smooth surface and speeds up the shoeing process considerably. In order to enable you to take a close look at the Unicorn shoe made with the new mould, I enclose another sample applied onto a transparent hoof model. If you compare the sample with the one I have sent to Her Majesty before, you can clearly see the improvements, which are mainly due to:

  1. The use of a direct measuring and shaping device by which the supporting frame itself is bent around the horses' foot and kept in the form by tightening one wing nut. This device replaces the old hoof gauge. It reduces the time to form the supporting frame and as before allows the tightening of the many screws of the frame away from the horses foot.

  2. The use of a P. U. foam cushion to cover the frog and the sole of the foot, areas which should stay free from the artificial horn. This cushion also limits precisely the space to be filled with the artificial horn, which can now be injected into the space which abandons all the previous work done with the spatula.

  3. The use of three provisional wire bars instead of one which makes the supporting frame much more solid to withstand the horse's motions during the 10 minutes it takes for the material to set. The three bars also hold the foam cushion in place.

  4. The use of the two millimetre thick latex hose which is pulled over the prefixed supporting frame and the hoof, being the outer form of the shoe mould. The acrylic material is then injected Linder it to fill all remaining empty spaces with the artificial horn.

This new procedure reduces the filling and shaping time for the acrylic material to one minute per foot. There is also no loss of material. Since the latex hose is translucent one can see which section on the hoof is filled and how much. One can easily distribute the paste like acrylic under the latex skin to one's liking with one's hands.

For your information I will add to this letter a photographic report of the making of an integrated horseshoe using the new devices (Unicorn integrated horseshoe shoeing process).

Attached to this letter you will also find our documentation of the results concerning the test of the new horseshoe at the Royal Mews. To me it seems most remarkable how much more abrasion occurred on the hind compared to the front shoes. This, I believe, is not only due to a good rider but also to a much to hard tungsten quality which led to the splintering of the tungsten plates. Such a splintered plate is visible on picture 3. The plate there is still held by the artificial horn surrounding it. In the hind shoe these must have been lost sometime after splintering. This could have led to an interruption of the steel chain in the supporting frame and to the loss of the front links which leaves the plastic links and the artificial horn unprotected. The manufacturer of the tungsten plates assured us, that they could supply us with a much softer substrate which will not break and still give the same protection. Such tungsten plates can be had at three weeks notice from Widia in Essen. We did not order these as yet because they ask for a minimum order amount of 300 plates

The condition of the front shoes is of such that one could expect them to last another shoeing period easily, and with the unbreakable tungsten plates, an this horse, the integrated horseshoes should be left an for two shoeing periods.

I would like to draw your attention to the two photos in the assessment of the trimmed hooves where the black spots around the former hoof nails are still visible in the sole horn. These I believe are bruises due to nailing which only become visible in white horn. I have sometimes noticed that these black areas around the nails start out being blood red right after nailing into the feet. This together with the findings in our holographic studies of the hoof allows the conclusion that considerable and remaining tension is created in a horse's foot through nailing and by the nailed an horseshoe which acts like a clamp holding the foot together which eventually can lead to its demise.

The amount of a horn that was removed through trimming can be estimated by how far the old nail holes moved to the outer rim of the hoof (picture five). I would also like to point out the scrape marks on the inner side of the right hind hoof (picture eight). None of our previous glue on shoes would have withstood the attacks from the adjacent foot, which was one of their shortcomings I mentioned in my letter to Miss Mary Francis. Today's materials especially the artificial horn which bonds equally well to PC and steel, allow all of the horses habits and works without risking the loss of a shoe. Our experience with numerous horses show, that after about three shoeing periods with the integrated shoe the hooves become immaculate.

I would like to suggest that the two sets, one in black and one in white, which you have ordered, should be applied by us using the occasion to instruct one of your staff in detail: or, which I would also very much appreciate, have Simon Creedy, one of the most brilliant Farriers I have worked with, come to Germany to be instructed about the structural adhesive shoeing process, and I assume, that, given three weeks notice, we will be able to deliver.

I'm very sorry that it took me so long to express my thanks, and the thanks of my partners Sergej Igrow and Michael Glueckstadt to you and the experts we met at the mews. But I wanted to be able to report "order executed" before I would return to the subject and unfortunately it took till now to come up with the jigs and fittings for the improved procedure. First of all I must thank you for initiating these considerable improvements and thus, like I have often experienced when involved with professional horseman, furthered our new shoeing technique very remarkably. I must also thank head coachman Colin Henderson for furnishing us with perfect conditions to put on and take off the shoes. As well as Dr. Scott for his veterinarian observation and opinion and also Deputy Head Coachman Nelson who took a very close look at the entire proceedings.

I would indeed very much appreciate if these gentlemen and of course Philip Hinson, who trained the horse, could make brief comments an the product and, even more, if you yourself would repeat two or three of the very kind remarks you made about the new shoeing system during our last meeting at the mews in writing. I add a few more of the brochures asking you very kindly to let them be handed over to the team at the mews.

Yours sincerely

Peter Stübbe

Dear Mr. Stübbe

Thank you for your letter dated 26th January together with the enclosures containing the artificial hoof and we were delighted to read of the improvements since our last trial. It would certainly appear that the technical advances will make this method of shoeing a worthwhile and viable option to the standard shoeing practice - in particular for horses suffering form certain foot related problems.

We would be keen to trial the improvements you have made to the shoeing procedure if you are prepared to make the necessary arrangements here in the Royal Mews at Buckingham Palace.

As a result of any future trial I would be delighted to forward our professional valuation of them, Perhaps you could therefore contact me with proposed dates for this trial and we will make a Bay and a Grey horse available for you.

Yours sincerely

Lieutenant Colonel S. V. Gilbart-Denham, CVO. - Crown Equerry

Thank you for your recent letter, to the Crown Equerry in reference to making a return visit, to the Royal Mews, and shoeing one of our horses.

At tile beginning of October, we shall begin our preparations for the autumn and winter ceremonial - r-his will provide us with an opportunity to test the latest design and technical improvements.

I should now like to firm up a suitable date for us both, and would like to suggest the week scarring October 4th, If this is suitable, perhaps you can confirm a day that week - OR another week or day?

Look forward to hearing from you and meeting you again.

Yours sincerely

Dear Mr. Henserson

It has been a great pleasure having been at the Royal Mews again an August, 6th., and I wish to thank you very much for your co-operation and help with the shoeing-process especially for the talk about improving the procedure by integrating the shaping device into each supporting frame.

Attached to this letter you will find three samples, one of the new supporting frame, one complete assembled mold of an integrated horseshoe and the finished product.

For the first time the supporting frame (the insert) looks like a horseshoe again right from the beginning. This insert can now be very easily adjusted to the shape of the foot.

The frame now has three additional parts which are partly disposable, but we got rid of a complicated shaping device and gained some speed. The metal tongues however should be replaced by plastic ones to make it easier to cut out the inner ends of them held together by the knurled nut. You will also notice that we have added to transparent plastic tongues at the ends of the frame. They are made out of Lexan the same PC material which is used for the plasic chain links. The two plastic tongues are necessary because we now use a very strong latex hose as the outer mold shell which would, without the tongues, pull steps into the heels of the shoe.

Everything else remains as you know it.

I am very interested to learn how the Unicorn Shoes are performing with the new tungsten plates and I would like to call you in one weeks time.

Yours sincerely

Peter Stübbe
