I just acquired a nice old percussion, 12 ga. SXS that is marked Atwell on the rib close to the breech. The seller bought it in an estate sale at Friendship. Supposedly, the owner passed away and his estate was being sold. The story goes that the gun is American made and was hunted with up until the time of the owners health problems. I've done a few Google searches but can't find a reference to Atwell made shotguns. Has anyone run across the name? I'll try and get some pictures up soon. I'd really like to have an idea of the approximate date of manufacture. Its in good shape and was well taken care of. It doesn't rattle, the hammer springs are strong, the hammers stand equally and the triggers are nice. With 32 inch barrels, it might just be a turkey gun!
