Manufactured around 1909-1912, with only a limited number made, reportedly less than 300 by some sources. 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. Much like the Webley-Fosbery, it had a hard time competing with standard revolvers and automatic pistols at the turn of the 20th century. Fixed blade and notch sights, with matching serial number "25" marked on the barrel, barrel latch, cylinder, ejector, and butt, the two-line address on the right sideplate and checkered grips.

Very fine, retains 90% original nickel finish with some flaking on the cylinder, and lightened markings on the right sideplate. Grips are also fine with some light handling marks. Mechanically excellent.
