L C Smith Damascus Barrel Marking Archived Message Posted by Robert Dobko on June 5, 2017, 9:32 am I recently acquired an L C Smith SxS Damascus barreled 12 G shotgun. Underneath both barrels SD&G has been stamped. There are no other stamps or marks on or under the barrels except the serial number. Does anyone know what the SD&G stamp indicates? Thanks....Bob Message Thread: L C Smith Damascus Barrel Marking - Robert Dobko June 5, 2017, 9:32 am Re: L C Smith Damascus Barrel Marking - Drew Hause June 5, 2017, 9:51 am Re: L C Smith Damascus Barrel Marking - Robert Dobko June 5, 2017, 1:57 pm   Searching
