Ellenbr: Thank you for all the information, I really appreciate your interest in this. I will try to get more pictures up later today, but the receiver is marked with crowned U. The 16 gauge barrel say Flusstahl Krupp Essen. The .410 barrell says Gusstahl Krupp Essen. The picture with the circled 16 is the watertable. There is also a Nitro mark on the 16 gauge barrel.
