Top (green) Mask:
C4 Gas Mask - Very gently used. Lenses are clear with no perceptible scratches. Green butyl rubber is free of any wear (cracks, fissures, etc.), straps are also like new. Passes the seal test (no, not the ice-cream, you junkies) with ease. Can send with a once used canister, but I would not trust anyone else’s filter - that’s just me being honest. Comes with a black nylon bag, which is nothing special.
Looking for $200 plus insurance and shipping.
Bottom (black) :
C50 Gas Mask - New. Will include a once used filter (see comment above about using used stuff) and a high quality nylon carry bag. $500 plus insurance and shipping.
