Older reg. Ist stage in good shape/stable IP, likely a piston. Dolphin logo only ID on it.
4000psi yoke, 2 HP ports, 4 LP ports.
Metal 2nd stage. Not sure if they came as a pair but has a very similar logo. Also in good shape.

That second stage looks very much like Sportsways Waterlung, albeit with a different logo and purge retainer.

As for the first stage I'm not sure, but it sure is very distinct with the wrench flats under the swivel.
 
1st stage is likely a Sportsway also. Found this on ebay. Certainly looks like my setup. Haven't been able to find any info on them for overhaul.

vdh used to have info on them i think, but not sure if the manual stuff is still up
 
The second stage is almost certainly a Waterlung 200 or variant built after 1977.

There are a few second stages with this exact design around, from the Diving Systems Z90, to the Beuchat Voyager. I suspect it has something to do with the Sportsways brand name and tooling being sold to an Australian company in 1984 and them building this regulator for several others.

I went through the whole manual. The 200 looks the most like the 1st stage I have, but nothing in that manual is exactly the same.
FWIW, I opened it up. Looks to be a pretty simple unbalanced piston.
