Early-war M30 gas mask set 'osn 1936'

A nice, well used early-war M30 gas mask set consisting of the canister, straps (damaged and retied), mask and spare lenses. 
 
The canister retains a fair amount of the original factory-applied apple green paint and is dated 1936 to the inside of the lid, alongside the makers logo and remains early Weimar eagle ink marking.
