Underhammer Pistol .34 caliber rifle. Unusual, appears to be an Allen 1st Model Pocket Rifle except for the integral rifle stock. Gun has no markings except for "8.0" on bottom of barrel. Barrel is 8" overall length. Metal is very fine. No rust, stains or pits. Stock is very good plus with a small toe repair at butt plate. This is a most unusual Underhammer and beautifully made!
