I put this here cause I don't want to violate the helmet's forum, by posting about something non-German.

I was given this helmet as a gift, anybody has any info about it, origin, value or anything would be helpful.Nicely marked OX and 1939.Thank you in advance.

looks to be early wwii brit mark II hemet,,nice and i saw one today at an Antique Mall for $75.00..it had the elastick cloth coverered chinstrap, so yours may be post ww ii use,with a leather liner and chinstrap that may be replacements.I believe that wwii helmets have black oil cloth liners with the above mentioned cloth-covered elastic strap...

The liner is not leather, looks like cloth covered with vinyl or something.It is marked 7 on the back, also the aluminum straps that hold the liner are marked 7 too.Thanks for all the useful info.

Some more pics.

the Greek army and the army of CYPRUS used these helmets post war into the 80s and where re lined of course so yours is probably country surplus
