Bought this today at a fleamarket. Looks to have had a black soutache which has been removed, as has the cockade. Has lining inside the dome panel and a sweatband, grommets look to be original, no sign of any stamps, but it was nearly dark by the time I got it home, so I will look tomorrow in the daylight. I will take more pics then as well, as these are not great.

It looks to have been showered on with lots of hot stuff, so maybe hot shrapnel, as the seller thought.

A very battered original IMO.

PS the skull is the closest thing I have to a headform
