looks to be a percussion shotgun....looks pretty old too
.......sorry cant help much.....think it would end up being a 12ga smoothbore......never heard of that maker...is thata double gun and i just cant see the far hammer and barrel? or a single barrel?? if its a single it would be left handed.......and id imagine worth a good bit more because i dont think many sidelocks were made left handed..i know not all to many are left handed today......back then i bet it was a rarity....though i may be way wrong......someone here should/might know more.....it looks to be in pretty danged good shape as well.....id hang on to it till you find out more....dont be messin with it or anything that might decrease value till then.....i know money isnt everything....but why take out a 1 of a kind rifle out and shoot it thats worth 6 figures? never know.....
