Can you identify this mystery gun?
I am offering a $500 dollar reward for the person who can identify (and support his claim) this interesting piece. Name and provenance (resources) are required to claim the prize.
I have a percussion revolving shotgun? It has a 5 chamber cloverleaf cylinder that fires the top cylinder thru the barrel. Internally there is a cased clockspring mechanism that can be wound up, which powers the hammer and rotates the cylinder. The barrel is a twist type, smooth inside and nicely browned in color. There is a number on the receiver (140) and on the handguard. The bore diameter is 0.648 at the muzzle and at the cylinder end. There are no other identifying marks anywhere. Barrel is 29 inches long with a bead front sight. No rear sight of any kind. No proof marks. The trigger guard is unusual in that the forward portion is much larger than the rest giving it a bulbous appearance. I can attach digital photos for further clarification. My local experts haven't a clue which includes David Condon in Middleburg. It is not a Colt or a Roper, but it is exceptionally well made (so it isn't a \"Garage Gun\"). If anyone can identify the maker I would love to hear from you.
