I've read a discussion on Facebook recently, where a guy firmly stated that long sizes of A-2 jackets existed in WW2. He provided pictures of original B3 labels that had "Regular" next to the size number. Consequently, he said, there were long/ large versions too. He hasn't posted any proof about A-2s, though. I'm not refuting his statement, I'm just looking for more information. Is it really something that existed?
