Manufactured in 1888. The scarce and desirable 6 inch barrel features the acid etched "Colt D.A. 38" panel marking on the left side. Matching serial numbers are on the frame, trigger guard and back strap. Includes a H.H. Heiser of Denver, Colorado, skeleton pattern shoulder holster rig, circa 1910-1920, that accommodates this revolver. The revolver and holster rig are pictured together and identified in Richard Rattenbury's "Packing Iron" on page 156. According to Rattenbury, this Heiser holster "was a knock-off of the original Zimmerman/Furstnow design with the addition of a flap leather cover over the grip and hammer area of the pistol."
