I am selling a Mountain High oxygen regulator model 00REG-1032-00 which
fits on a standard US bottle type CGA-540. It has an "L" shaped
connector on the low pressure side. There is no provision for a meter on
the high pressure side but if your bottle is metered that shouldn't
matter. I bought it in the Summer of 2009, it has 2 flights on it and
works perfectly. $110 shipped to CONUS.
