Hi! I'm new to the forum. I have an early fixed bail, front seam helmet. Lot number 207c. The liner is inland with unpainted A-washers. I believe the liner to be early as well. The helmet is battleship grey with the numbers E 307 painted on the front. Does anybody know what those numbers mean? I've been told it could be the hull number of the ship the helmet was assigned to. If so the USS Finnegan had the hull numbers DE 307. Could it be tied to that ship??? Thanks in advance for any help!
