Inspected, unused Navy surplus:
Manual PFD: pull string to inflate with CO2, or blow into tube.

Includes  33-ounce CO2 cartridge,
AND the Whistle, tow line, and Firefly   xenon ACR  Strobe! (worth price alone)

Note regarding the photos. I have this PFD in Stearns brand as well . They are the identical military spec,
 and share identical brand valves, whistle, and strobe.
- virtually indistinguishable - YOU GET one of my last Mustangs.

 
Outside Continental US WILL NOT INCLUDE CO2 Cartridge
