Vest, Pneumatic Life, Type B-4. By The Seamless Rubber Company. Date of manufacture is January 18th 1943 making this a relatively early example without the later 'top' strap. The material is in excellent flexible condition with good colour and relatively light soiling. The vest retains all of its securing straps in very good condition. It also has both CO2 bottle holders complete with screw-on covers and pull-strings. Both inflation tubes/valves are present and in excellent flexible condition. Evidence of dye pack removal. The vest has various AAF stamps/inspection marks and later inspection dates. B-4's were procured specifically for use by the AAF whereas the later AN6519-1 was also used by the USN. A very good example. Stock code MW24844.
