First Stage for shop air blower ..

Is that the mk5/10 clone?

No idea! I'm not up on all the brands and identifying them. I *think* it might be a DX2, post 1995 based on one doc I came across. Though the one I have is chrome, not brushed finish... It doesn't have a bottom port like the SP MK10 seems to have.

I haven't taken it apart - it seems to be locking up well enough - checking for IP creep now that I have a way to vent it. I have the IP set to about 125psi.

LDS had a clearance on HOG D2s that they ordered for a local public safety dive team. They ordered DIN regs but when they came in decided they meant to order yoke regs... (Why? I can't figure that one out!) But, I got a couple of those HOGs.

Coming off the first stage, I stuck on a small variable pressure regulator from Ingersoll-Rand. Because while I am usually of the "MORE POWER" school of things, sometimes I don't need 140 PSI. I stuck a schrader valve off of one of the LP ports to make it easy to drain if I don't have anything hooked up to it and the valve gets turned on (saves me from having to hunt down and plug in a hose w/ air gun) as well as a button SPG on an HP port. I have one of these at a bottle at the scuba bench and one at the gun cleaning bench.

Sometimes I prefer a bit more pressure than is available through a regulator

No opv

Over-Pressure Relief Valve (User Adjustable)

The over pressure relief valve (OPV) screws into any available first stage low pressure port and provides protection from first stage failure.
