Hello friends!
I recently bought an M40 helmet shell in good condition for 25 euro (30 dollars). It was already painted, I really hope the guy painting it wasnt serious. You can see markings inside the skirt, first is hard to read on the photo, but it seems to be 22401. The other marking ,however, isnt readable. When I saw it for the first time i thought its SE64, because I was told its an 64 size helmet. I tried measuring it, but it seems i do it incorrectly, because it turned out to be 65 cm
Then i saw a photo on the internet - the differences between manufacturing in various factories. My ventil is not in the center so it can be ET or Q. Ive never heard of those differences so I´d like to ask if someone knows who manufactured it.

I stripped off the paint with weak chemicals so wouldnt damage the original paint if some was there. Only little bit of original paint was left on the outside. I decided to re-paint it, because some parts are stripped to bare metal. However i was thinking about using filler. (I dont want it to look like it just came from a factory) but to use it only where big holes are. Then, paint it and texture it. A friend of mine has some feldgrau paint left in a spray can, so I would use it. However I would like to ask if i should use alumunium oxide or saw dust. Ive read thet the SE used aluminium oxide a lot.
Thats all for now, thanks for the reply!
