Here we have a .36 side x side stainless steel percussion Derringer possibly made by Hoppes in the Ethan Allen style with 4" barrels. Although a small gun it is very heavy for it's size, very solidly built, a quality piece but it does not show a manufactures name, just a 2024 London Proof reading 1.5 GRMS NOT Nitro. Very unusual piece in what looks like unused condition.
