George Fosbery V.C. is best known in firearms circles for the Webley-Fosbery automatic revolver, but he experimented with several other firearms designs as well. This particular one never made it into commercial production, but it uses a bolt design very reminiscent of what Johnson and Stoner would use 50+ years later, with six independent locking lugs around the circumference of the bolt head.

This firearm actually began as a pump action rifle before being converted into a shotgun (using a Winchester barrel), which makes it all the more interesting. It was originally made circa 1891, and later converted from a rifle into a shotgun (hence the 1909 model barrel).
