I think it may be ww2 vintage, but the info on the pics is to hard to tell. I had one like it and in the nomenclature it said "Army Air Corps" which made it ww2 vintage.

I see a type #. Maybe that could localize it down. It is pretty interesting that these things have not really changed in decades.
