OK boys and girls, can anyone please tell me what brand/model of regulator I have here. I got one of these used but new condition and was wondering what brand it is so I can hunt down some parts for it. It is a diaphragm with a 300 bar fitting on it, four LP ports and two HP ports. Thanks in advance for any help

Looks like it may be an early model Scubapro (one of the first new look diaphragms). Could be wrong though.

let me add that the two "plugs" on the ends are not ports, they are adjustment/take apart covers, not plugs like the scuba pros with the ports on the ends

That is correct. This is a diaphragm model unlike those with the end ports that are pistons.

Your picture on the left shows the one allen key hole which comtrols your intermediate pressure. It is a threaded cap that increases/decreases tension on the spring, which in turn pushes on the diaphragm.

Your picture on the right shows the end that if removed, will reveal a smaller spring and the high pressure seat. If you look at this part the groove in the end of it will give a good indication on how bad the reg needs service.

Hope this helps.
