I have had this SCUBA tank for a number of years. Still has air in it, although the hydro/visual are out of date as it hasnt been used for a while. It is a vintage steel tank, I believe a 72cu. The size is about 24"x6" if that helps. The earliest hydro stamp on it is '59 and if i recall it is a US Diver tank and the valve is also stamped US Divers Co, Los Angeles, CA. Asking $70 and dont want to ship this. I am in the Dallas, TX area
