In World War II the Liaison Pilot Wing was awarded to pilots who flew single engine “grasshoppers” in and out of small airstrips and in some cases dirt fields or even roads. They did what today we would expect from helicopters. The wing was established on Sept 4,1942. One very unusual factor is that these pilots were not part of the Air Corp but rather Infantry. That is why they were Liaison Pilots. This is a very well made sterling silver museum quality reproduction in standard size pin back of these wings with pin back.
