Up for sale is a mixed parts working Black Powder Rifle. The stock appears to be a reproduction. The Barrel is from the late 1800's with very strong rifling, fitting snugly in the stock. Stamped on the barrel is J.H. Johnston Great Western Gun Works Pittsburgh, PA. The lock, hammer, butt plate and trigger guard are from an M1861 Springfield. Overall it is a very solid and simple rifle. Hammer and trigger function properly with a little play in the trigger that does not affect normal operation. I'm guessing .44 or .45 cal percussion, but not a 100% sure. Feel free to contact me with any questions.
