I'm thinning out the M1's in the closet and noticed this one had something painted inside it. I'd never noticed it before and I guess the light hit it just right. I can't really make it out but to me it looks like a name, possibly a serial number, and Port (something) Casablanca. I've tried to photograph it using different filters and contrasts on my camera but I can't seem to make it any clearer. The helmet itself is not much to look at and I almost put it in the 'sell' pile but I'm intrigued by the writing in the helmet. Perhaps I'm seeing things that aren't really there. I just wanted to post it for opinions and see what other sets of eyes make of it.
All thoughts and opinions are appreciated
