This vintage overcoat was made in 1918 by Cohen Endel . . . of New York and was distributed by the New York Depot quartermaster. The coat is double breasted, with a belted back and buttoned throat latch. There is a secondary stamp from the New York Depot, stamped Marvin Falk and what looks like 1933. The belt-back is is sewn over the tag and lining, and from its construction, looks like it may have been added later. There is a army air corps patch on the shoulder, obviously added later than WWI, however if the coat was re-issued in the 1930s, it would likely have been added at that point. The As is typical of coats of this period, it is only partially lined.
