Manufactured around 1909-1912, the Union Automatic Revolver bears a strong mechanical resemblance to the Webley-Fosbery 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 deviations are that the hammer is mounted to the housing on the Union, no manual safety is included, and the mechanism is capable of a double action fire. Only a limited number (less than 300 by some sources) were made, and much like the Webley-Fosbery it had a hard time competing with standard revolvers and automatic pistols. Fixed sights, with "36" on the barrel and cylinder, "38" on the butt", two-line address on the right sideplate and checkered grips.

Fine, with 60% of the original nickel finish, with flaking to exposed brown and gray steel concentrated on the grip straps and the back of the housing, mild handling marks and light spotting. The grips are very good, with some dings and flat spots. Mechanically excellent.
