United States Army Air Forces / USN / USMC. The marking are very light.. But I can see a 1943 date - (lower right). Both C0 2 inflators are intact - (but no Co 2 cartridges). It looks good for your display , I'm not sure it will still hold air today.
I wouldn't recommend depending on it to save your life! These are getting hard to find today. These were used on any American aircraft that flew over open water.
Commonly used by the 8th Air Force B17 bomber crews in Europe. Don't pass it up - early War versions are very scarce. A must have for all WWII militaria collectors!
