A genuine U.S. Army Vietnam War era steel snap link carabiner. These snap link were used by Airborne and Special Forces and were used for rappelling from helicopters or getting across rivers. The spring back snap link is in working order, makers marks WYOTT with the date 1972 on one side, 'U.S.' on the other side. A scarce item and very hard to find in the UK especially in working order in this condition. A great accessory to add to suspenders or rucksack.
