Sergei Sikorsky was with the H-37 when the type was based with the US army in Europe,serving his time as a mechanic I believe .Imgine he had plenty of work keeping it serviceable.
Years later I came across a bunch of them in a yard next to Davis Monthan in Arizona ,minus their engines and instruments etc that had been sold off.i went to examine more closely but was warned off by the owner who pointed out that the cabins were popular hiding places for the local rattlers!
