My ten gauge Thomas Golcher marked Lindner hammer gun has a well constructed beavertail. It was owned by Monkton, Maryland shooter Jerre Godwin, whose name is engraved on the rib. His exploits in the pigeon ring and the trap fields are well documented in Sporting Life entries available on LA84. I doubt that his ten gauge was in use beyond the turn of the century because of rules enacted in the 1890s eliminating the ten gauge from competition. This gun is probably the earliest competition shotgun equipped with a single trigger and beavertail forend.
