John Krider was a name well-known among 19th-century American sportsmen, particularly in Philadelphia, where his gun shop became a staple of the local sporting community. Situated at the northeast corner of Second and Walnut Streets, Krider’s shop wasn’t just a place to purchase firearms; it was a hub of innovation and craftsmanship, where the latest advancements in gunmaking were adapted and perfected for the American market. Among the many firearms that passed through Krider’s hands, a particularly notable piece is a 12-gauge pinfire shotgun that exemplifies his blend of European influences and American ingenuity.
