Hi William! Looks like a M40 relic with the surface recently painted.
A bad deal for 20 quid? Thanks for the answer!
Bad deal or good deal is about you, about what you like to collect, personally, i don't want repainted helmet (post war), but if you are starting collecting could be a good start, you can even remove the paint with some chemicals (that i don't know which).
Anyway, 25€ or so isn't a bad deal for it, it's a small amount of money, although it had been a bad deal, it's very cheap, paint is fake, but shell it's a original M40 relic
Thats just what I wanted to know! Thanks very much!
