A very rare and impressive collection of Ulan casques Maxime, congratulations. I have been lucky enough, to do restoration work on 4 of the original leather ones and their construction is totally unique! I am most interested in your felt tschapka as they are exceptionally rare. I was offered faux examples when I was a younger collector, but did not buy them. We have all seen so many copies/fakes for sale. James and I encountered one original at the last SOS Show and we took pictures but it was damaged. I had never handled a real original before and it was an extraordinary experience. Some extra... close up photos of your original filz tschapka would be very much appreciated when you have time. My thanks.
