A genuine U.S. Army steel snap link carabiner. These snap links were often 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 O.E.C with the date 1979 on one side, 'U.S.' on the other side. A scarce item and very hard to find in the UK. A great accessory to add to suspenders or rucksack.
