Here we see a well-traveled M1911A1 .45ACP Government Issue long slide.
It’s a mismatch gun that likely became such in some long forgotten Army armory, with a (likely Great War era) Colt-marked slide and a 1943 U.S. Army-marked Remington Rand frame from the Second World War. As such, it or at least components, served in both World Wars, probably Korea, and definitely Vietnam.
How do we know the latter? Well, the gun, SN 1431274, was captured north of Da Nang in August 1965 by Warrant Officer Class 2 (WO2) Kevin “Dasher” Wheatley, Australian Army Training Team Vietnam (AATTV). The weapon was recovered from rom North Vietnamese Forces who were believed to have captured it earlier from ARVN forces or the Americans.
Wheatly passed it on to war correspondent Pat Burgess as a protective weapon when Burgess suffered a cut on the elbow and had to go to Da Nang accompanied only by some sketchy ARVN troopers.
Wheatly went on to die just two months later in an incident that would see him receive the VC. His medals came into the Australian Memorial’s collection in 1993, joining the 1911 on display.
