Quoted Text
these are the authentic worn by German soldiers in World War II
Oh I believe that. But quite a bit of stuff was produced and used well post WW2 in (almost) unchanged form both civilian and military. Ie. the white sport socks and grey woolen socks issued to me in 1987 where identical to the white socks I used privatly and the grey ones issued to me when working at the local coal mine(1).
So that underwear can be used on a civilian clothing line for a REFORGER scenario in the 70s just as well.
(1) In german mines work cloth was/is issued by the company. That includes underwear.
