I have an Airgas model HP 80 oxygen cylinder and Radnor regulator. Cylinder is current (next hydrostatic test date is 2018, so you have plenty of time to exchange it for a full one) and is approx. 1/3 full. This is a 7" diameter x 31" tall cylinder.
$120.00 firm. (the regulator alone is $100 new on Amazon). I can bring to the MCA meeting tonight or the Greater Detroit auction tomorrow.
Call or pm with any questions.
