Manufactured around 1909-1912, the Union Automatic Revolver bears a strong mechanical resemblance to the Webley-Fosbury Automatic to the point where the base principles are virtually identical: a top-break revolver frame is mounted in a spring-loaded housing and grip assembly, and on discharge, the frame is driven backwards by recoil, revolving the cylinder and re-cocking the hammer. The main deviation is that the hammer is mounted to the housing on the Union and no manual safety is included. Fixed sights, with a repeating "21" or "20" on several components and the address on the right side of the housing. Fitted with a pair of U.F.A./American Eagle grips.

Fine with 75% plus original nickel finish, showing some light scratches and flaking overall. The grips are good, with some dings and flat spots. Mechanically functions, but is very stiff.
