My very first gas mask

The Finnish Nokia M61 gas mask was the very first gas mask I owned, I was given it as a novelty gift.
Since then, I now own 60 individual gas masks with many others as duplicates.
The Finnish M61, a US M9 clone, often turns up cheap on the surplus market and is worth grabbing, it's quite a comfortable mask.
However please note the M61 takes obsolete 60mm NATO filters, so you will need a 60-40mm filter converter if you want to actually use the mask.
