The rubber is supple and there’s no cracking. The foam disks are slightly yellowed from age but they are soft and usable and the bag is not stuck together. The strap assembly is new. It’s probably 1950s vintage. I’m including a metal supply connector. The item “Rare USAF/AAF A-8 Constant Flow Oxygen Mask FREE SHIPPING” is in sale since Friday, December 08, 2017.
