These were the first of the M-37 trousers made from existing HBT stocks in Blurred Edge, Oak-A, and Oak-B (originally made for the 1943 production of smocks).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 30,32,34,36,38,40,42
