Never give up ! I'm not really into helmets, but walking past a local 'junk shop' a few months back, there's an airborne-type helmet amongst the junk on the pavement. Nice - must be a post-war one. Picked it up, turned it over, and faintly stamped into the liner leather is ' BMB - 7.3/8 - 19.44 '. It's a 'real' one.... OK, it's the later, web-chinstrap one and didn't go to Arnhem but it's 'of the period' 'How much for this?' 'Only came in this morning, mate - ten quid'. Doesn't happen every day - but it's nice when it does !
