Gasmasks one with trunk dated 1037??

[skalphunter]

I have these 2 gasmasks one with trunk on dated 1937. Can maybe somebody say something about these pieces. Different numbers are on those masks as well as swastika abnahmestempel. My biggest question is for what the mask with the hose was used.
Thanks in advance

The gasmask with the hose is a GM-24 but with a wrong filter screwed on it. GM-24's were initially used in the Reichswehr but were later used by FLAK crews. The original filter of a GM-24 is a large boxlike filter. They are quite uncommon and a great score but alas your is missing the filter and bag. Still a nice score though.

The other seems to be a standard GM-30 1st pattern, these were phased out of service because when the GM-30 (3rd model) with the covered exhale valve came out, some GM-30's were converted to GM-30 3rd model specification by placing a cover op the rather exposed exhale valve and are known as the GM-30 2nd model. Eventually all GM-30's 1st and 2nd models got a second life as Luftschutz gasmask. Yours is a GM-30 1st model. The filter is also not correct for this gasmask.
