Are you crertain about the 'date' (1943) under "Medical Department" ?
I'm just making this remark, since there's been quite a lot of white towels thrown onto the local market over here ! I'ven seen large numbers of the small ones, and they all received a 'date' stamp by some unscrupulous vendor ! It's easy to tell, sometimes the fonts are different, and the ink hasn't had time to fade ...
Of course, they can still be used for re-enactment .
