These were the first of the M-37 pattern trousers made from existing HBT stocks in Blurred Edge, Oak-A, and Oak-B (originally made for the 1943 production of smocks). The 1944 Dot pattern followed shortly thereafter. They were usually sewn on the brown side of the double-sided print but the green side was also used outside. Sized like our 44 Dot trousers, these are available in sizes 30, 32, 34, 36, 38, 40 and 42 with either Brown or Green side out.
