1st stage

[Snorkelinglilypad]

I just checked and it is the TR-10 that has a knurly bit, just underneath the swivel. Of course this is a complete different design to what we are looking for here.

This thing is a bit of a mystery to me.

I appreciate your response

Tusa or Tabata TR-100 and TR-200. But they don't have the tank attachment inline like this one.

Thanks for your help

That riffled cap is exactly what throws me off. It looks like the Aqualung Calypso, except that riffled cap. No markings on the body would mean that it is not an Aqualung, as the serial number would be somewhere on there.

Palantic has their regulator manufactured by Alloy Star. Depending on how Scuba Choice, which carries Palantic as their house brand, ordered their "Palantic" regulators, there may not be any markings on it.

Regardless, I do not know any Alloy Star / Palantic first stage that looks like this.

I have reviewed the 1st many times and there are no markings. Crazy but a good challenge. Inside is clean and breaths very well

How about a generic argon reg?

For me it's quite clear an Aqualung Calypso/ Aquarius 1st, '94-97' model or a clone of that model, because the cap is a bit different with it's riffles to what I remember.
Everything else is exact that model, so I guess it might be the last model of those Calypso/Aquarius, that's why it shows on the schematics only the smooth cap.......

Thanks very much

Yes spotless and breathes perfect, pressures are good and very stable

Just engrave your name across the end cap and call it a bespoke unit made for a VIP.
