Several years ago, an old family friend gave me an M1816 conversion that was cut down to almost the same length as an M1841 or P58 Enfield. The gun itself is rather incomplete, no bands, ramrod, butt plate, etc. I can't say for sure when it was cut down, but it looks like it was done sometime in the 19th century. The man who gave it to me had it for decades and it was already that way when he got it. I can't see someone cutting it down for use as a shotgun, although it could have happened. My theory is that maybe it was cut down for cavalry use early in the CW or even the Mexican War. Is this just wishful thinking on my part or is there evidence of such use? I appreciate the help!
