I inherited a Parker Brothers side by side shotgun. I was hoping someone could tell me the model and the grade, maybe even the value. It is a 10 gauge, with 32 inch Damascus barrels. It has external hammers. On the left side of the receiver, there is an engraving of a pointer with 2 birds. The right side has a different dog with two birds. On the bottom there are 2 pheasants next to a fence, and another bird below the patent date of Mar. 25, 1875. There is a shield on the top of the stock, but I can't make out what it is because of wear. There is also what looks like initials or a signature engraved behind the trigger guard. I can't make that out either from the wear. I learned from the serial number that it was manufactured in 1882. It is in fairly good condition. There is wear from alot of use.
