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.
