I forgot to post these pictures showing some differences between early and late model air-packs. The "Main Body" has 2 designs, the one on the right (earlier design) has
provision for an 'O'ring , while the later design has an extra bolt hole (not used by the military). The "Control Valve Piston" on the left is an early design, it has a shorter body, it also has a longer stroke. The right side one is the later design.
Hope this helps.
