I have an old side by side that I am trying to identify and find some history on. I believe it is an old black powder Browning Belgium shotgun. It has a barrel length of 29 7/8", inside chamber diameter of .906, double hammers and triggers, and on the underside of both barrels is stamped an oval topped by a crown with the letters ELG inside the oval. Also stamped in the same location is a diamond with 12U stamped inside it. The serial number is 22137. There are some other markings that I take it to be just inspected by type marking. Such as a backwards 33.
Anyone have any ideas on this at all? Or can anyone point me in the right direction?
