M38 gasmask with early short canister marked L.S.

Very nice original M38 gasmask complete in a short early manufactured canister. The canister shows a nice L.S. Luftschütz ink stamp on the bottom. It also features a nice leave ticket from the Hauptbildstelle der R.L.M. Reichsluftfahrtministerium. Very nice and interesting example which would be a great research object!
