Years ago, at separate times, I had two Committee of Safety muskets that may have been used in the American Revolution. Later, I had a Harpers Ferry 1803, not used by L&C but maybe used in the Second War of Indepence. I still have a 5th Model Burnside, the second most popular carbine of the ACW. I also have a Springfield 1866. With the 1866, there is a chance it may have been used in the ACW, then after conversion, the American Indian Wars and since it shows evidence of making a trip to Bannerman, perhaps it went overseas to equip some fledgling army.
More modern firearms include a Model 1898 Krag, a P08 dated 1942 and a S&W Model 1917 sold to Brazil prior to WWII.
Of course, I still have two of the handguns I carried when I was in Law Enforcement.
