WWII USAAF Co2 cartridge dispenser. B3,B4,B5 Life vest

Missing parts from your WWII USAAF Life vest?

Available are spare C02 dischargers as used on a variety of WWII life vests ("Mae Wests" as they were humorously called by airmen), such as the AAF's B-3, B-4/AN6519 and B-5 vests.  They will also fit the USN vests, such as the Mk. I and Mk. II/AN6519 life vests as well.  In good condition, these units are supplied without the small CO2 canisters.
