This Air Force/Army life preserver best was manufactured in either 1943 or 45. It was inspected however the stamp is very faded and I couldn't make out the date. This preserver still holds air and the rubber is soft and pliable. Both empty CO2 bottles are in the side cylinders. This is a B-4 Mae West life preserver and was once owned by Jerry Bendrom of Ironwood Michigan.
I looked like it belonged to someone before that by the name of Peterson but the name was scratched out.
