Caliber 32 rim fire. Factory engraved with full coverage. Could very well have been engraved by L.D. Nimschke as it shows his quality and style. Gun features a detachable nickel plated wire stock. I believe this gun was made from the #2 vest pocket pistol and a 32 caliber 18″ barrel. A very unusual gun in excellent condition. Retains most of the original bright blue. Original sights that include Beach’s combination front sight and a semi-buckhorn rear sight. The receiver has most all its silver finish remaining. 2-piece pearl grips are in fine condition. Comes in a brown leatherette case that shows some discoloration but is completely intact. This is an amazing little outfit. I have only seen one other that was similar to this.
