Might have missed them but did not see any of the Winchester Self Loading rounds. .32, .35, .351 and .401
The .351 WSL was actually used in WWI, in aircraft and in the trenches, making it the first autoloader to be issued in any quantity.
Of course, there were also a plethora of blackpowder rounds in the 1800's, most of which are now highly collectible.
Nice display! thanks for posting it.
