Took delivery on this one last week. Fantastic M17 Leather gas mask which is pretty much complete. Has all mask straps in good condition, leather is still soft and supple and lens are still in place and a little cloudy, with spares in the top container. Filter is nicely marked "14.4.18". The real bonus is the can, has the small carry strap and its named. Text says:
8. Komp ? G.R. ?
Anyone have any idea on the Question marks?
