Friends, i wonder if you might share you thoughts on this recent helmet i found this week please. It was covered in surface rust when found, but i have wiped down to reveal a tan paint, with traces of black base coat it think. the only helmet markings i can see are E or F37 near the helmet rivets, and the liner is a 7 1/4 TTC 1940. any comments very much appreciated, thank you, Shaun
