Thanks, the pics would be great and I'm sure others here would like to see them as well.
I think the first "universal", as in adopted for all of the military, cartridge was the 50-70. Then came the 45-70, 30-40 (first smokeless round), 30-03, then the venerable 30-06. Few oddballs like the 6MM Lee Navy and such floated thru but those were the main ones as I recall. Any real experts on this can fill in if you would.
There was a great article in the American Rifleman maybe a year ago about the Sharps rifles like the one I have. I think it was about them being issued to the 2nd Penn. Dutch, a sharp shooter outfit that would be held in reserve and moved into hot spots on the line. Since I pass these magazines along to others I don't have it for reference anymore for more details.
I'd like to see that article on the tape primer feed conversion, the old Sharps rifles with the side hammer came in many variations and it's interesting to see them.
