2x PST 104s. They are slightly mismatched. One is a '78, the other is an '84. The 84 is identical to my mid-90s tanks, the '78 has a slightly more rounded butt. The weigh very slightly differently. Great shape inside. Out of hydro for a couple years. No valves.

I will take $300 for the pair. Great singles as cavern or intro diver.

I can drop them in cave country this weekend.
