I'm trying to find some information (age, history, value) about a shotgun I saw at a pawn shop last week. It is a 16 ga. SxS with external hammers and damascus barrels. The rib is marked Sempert & Krieghoff, Suhl. The water table has the following stamps: S, W and U under a crown, 16/1, 16 in a circle, a bird surrounded with feathers (this looked more like the Austrian one that the German one in the back of the Blue Book) and the number 3828. The bores look good with a small amount of pitting. The receiver and the rear of the barrels have engraving. There is a silver inlay around the rear of the barrels and some on the receiver. All blueing is gone on the receiver, some is remaining on the barrels. The wood is in good shape with no cracks but someone has put a coat of varnish on it. Price was $899. I've stayed away from damascus barrels since I shoot my SXS hammer guns (28, 20, 16, & 12 ga) regularly but this one got my attention. All I've been able to determine is that it is pre-WW II. I would appreciate any information about it. Thanks.
