A nice nearly mint USd looks like a 50 cu ft with a strange but mint valve, (which I have never seen this type before with the extra plug) and a Aquadiv regulator , in the original box. Note the harness is also mint. I have the original USd box the tank came with and the two manuals. Pix to follow if I dont mess them up. The aqualung decal is box worn, from rolling around in its box all this time. Tank had some air in it when I popped the valve.



there are at least two regs there, because I saw the accordion fles hoses all jumbled around, sticking out behind a box, which unfortunately I did not have time to see. On my next trip... perhaps the gods of vintage diving will be generous...as always I am thankful to them for the bounty provided.
All this stuff is either unused, or as new unused, or very gently used the tank is 1961
