Answer 1

Have the 12 gauge, single shot palmetto arms co., electro steel choke bored, patented august 12 1913. It also has 2 other markings on it, 657 EE on barrell and in the chamber. Then on the small forward snap off stock is also is stamped in the wood 7 B 1, I read that is an indicator as to where and when it was made. What can you tell me about this weapon? Thank you so much for your time, Frank
