Do you have any other pictures.
Aged repro from the look of it.
This helmet has some problems, 1- the outside is very dirty and has paint loss but the inside is brand new and has post ww2 liner band added to it. I don't like this one
it all looks artificially aged to me & as gel65 said the liner sweatband is not a WW2 version looks to be 60's onwards type !
OD green sweatband definately caught my attention. There are more so scrapes than actual wear to the helmet as well.
