Dive Rite Stage Regulator

Dive Rite stage regulator.  Could easily be setup for single cylinder diving or otherwise, but in current configuration it's perfect for a bailout bottle, stage bottle, etc.  Dive Rite first and 2nd stages with a 40" LP hose.  HOG brass/glass SPG on a 6" HP hose.  First stage is DIN.  Service history unknown, however regulator has been tested and tuned and works great!
