Pilot of the Red Army Air Force command staff of the 1935 model, film studio?

Quite an interesting and unusual find of our store is a flannelette cap, sewn in partial accordance with the TU of 1935. The only difference is in the material of manufacture (the flannelette cap, wool edging, the inner lining of the lapels of the cap is not provided, there is no sewn blue star). There is an unreadable stamp on the cotton lining, probably a studio stamp. We assume that this cap was sewn after the war at a film studio or in a theater as a prop for filming war films.
