This is, by far, the LARGEST size (M62) I've ever encountered in real life of one of these. I kept it as a super uncommon piece, as it came with Hauptfeldwebel rank boards, and was even too big for me at my biggest. It's about a 3XL-Regular, which is awesome for someone who is a big boy and can never find an original in that size. Today is your lucky day, and I'm happy to pass it on to you.
