Rare CS Shattuck 12 gauge shotgun. Vintage.

I’m letting a few things go to finance another project. Available is this rare and unusual Vintage C.S. Shattuck 12 gauge shotgun. Two triggers. One to open, one to fire. These do not come up for sale very often. A must have if you like different and unusual shotguns. It’s a single shot, black powder shell era, late 1800s. It has never been refinished, and has an overall dark patina. Stocks are good. The very tip of the hammer is missing a small piece. The price is negotiable to fair offers. PAL and transfer is required. Thanks for looking.
