I just bought a Peabody carbine from a coworker. The stocks have the remnants of an old brown paint job and the meta is rusty but doesn't seem pitted. It won't hold full cock and the uncleaned bore looks....well, 150years old. Anybody have an idea what .50 caliber round it might be? Maybe 50-70 (I hope) or 56-50 Spencer? Any help is appreciated. I'll be carefully tearing it down soon to see what's what.
Best, Thomas.
