Help needed to identify this reg brand.....

[axxel57]

Hi guys

Found this remarkable reg, but after quite some search I cannot identify the brand ( the model should be clear).

It's a 90' degree unbalanced piston 1st ( don't remember having seen ever one before) with a standard unbalanced 2nd.

IP after service is tank full 128psi, tank 600psi it is 105psi.

The Polaris 2nd has an adjustable orifice, but the LP hose connector is not imperial, seems European, the 1st stage prorts are all 3/8 ports ( including the hp port), but a special LP Hose is needed with the 2nd stage connector with European threads.

I thought I have seen thhat logo before, but can't remember.

With the 3/8 hp port it should be from the late Sixties or the Seventies, thought of Froschmann or Tauchtechnik, but it could be maybe also Spiritechnique, Beuchat, Nemrod or Cressi.

Anyway an interesting 1st stage design........

I can't really help with giving an exact manufacturer, but maybe a few pointers.

Cressi, Froschmann, Tauchtechnik, Spiro and Beuchat have decidedly different logos. I can't recall having seen this logo, the only ones that came to my mind were XS-Scuba, which is of course of no interest here and Parker Diving, which is not quite a perfect match.

The only Polaris second stages I know are from AMF, Voit, Coltri Sub, Cressi (Several), Kawasaki and Tauchtechnik, but none fit closely enough.

The Tauchtechnik Polaris for example looks very different:

As for the first stage, that has me equally stumped. There a few 90° unbalanced pistons I can think of on the top of my head: Siebe Gormans - Neptune; Typhoons - MKIII; White Stag - Depth Finder.

The White Stag looks somewhat close, but not close enough.

I’m thinking cressi but don’t know why. I do wish there were more 90° unbalanced pistons around.

As the OP previously posted up a Kawasaki I am wondering if it is an earlier version??

Hi Guys

Just wanted to share some pics with you.

Just got me a quite rare Kawasaki reg from the late 70ties or earlier 80ties I had been looking for for quite a while.

The particular thing about that 1st stage is that it is a balanced inline piston 1st, which works quite well (5psi difference between full and near empty tank) with a unique design.

Unfortunately up to now I was not able to remove the HP seat (retainer) without damaging it, but for the specialists it should be clear how it works. The HP seat is integrated in the retainer, not in the piston.

The components are good as...
