This pistol is not in great condition but it is a very early model. The 4 digit serial number puts it as an 1878 or 1879 manufacture. The caliber is .32 S&W. It has been rusty but was heavily oiled and wiped down. There is some pitting in the bore. Everything seems to function correctly but you would definitely want to have a gunsmith inspect it before attempting to fire. SOLD Could possibly trade it toward a .270 rifle for my son. Would need to be fairly light weight but not a youth model. A synthetic stock with 22" barrel would be ideal.
