Vall, You should google "The Beginnings of International Rifle Match Shooting" by General George Wingate who was the Captain of the International Team. I believe the US team was made up of members of the Amateur Rifle Club. Hepburn made up his and Fulton's rifle and there was about an even mix of Remington and Sharps rifles. The first "new rifles" were delivered to team members around March of 1874. Try outs were held at the end of May and the match was held at the end of September which gave the members a mere 5 months to get ready. As you say, it was quite a fete. Fulton's rifle came up for auction about 13-14 years ago and I was surprised that it didn't go for more money. Probably because not many of us left that are into this history. Enjoy your find.
