I asked a question about this piece a while ago (on whether or not the go for the auction) and it finally arrived! I’m very happy with it, a nice addition!

Having had a look around of it, I’ve found what seems to be an ‘F’ on the back interior rim, some stamp in the metal on the chinstrap buckle piece in the space between it and the shell (hence the bad photo!) and I seem to have unearthed what may be the original WW2 paint. It seems to have three layers, the exterior paint (no idea on that) post war olive (seen on the interior) and the original paint (see in some photos of the interior)

Thanks for looking and have a good one!
