Hi everyone!
Anyone familiar with this first stage?
Is it worth rebuilding it?

Cheers

I will ask the mods to move this to the regulator forum, as it will get more response.
 
I don't recognize the marking or yoke knob but the overall design looks like a Tekna. They made a few flow through piston designs that look a lot like that. If it's a Tekna or a clone, it's going to be hard to find a HP seat for it
 
I have several Tekna first stages and I still use them as faux Mark Vs, I even put the heavy SP yokes on them. They are virtually identical including parts swapping to a SP Mark V. The HP seats are the same. The only difference is that the Tabata/Tekna/Oceanic/?? versions have a round yoke knob and a domed HP seat carrier instead of the flat exterior of the Mark V seat cover. I do not think the OP first is a Tekna. Not one I am familiar with anyways. And that does not look like the Tekna logo either. on the yoke knob.

Dang Nem, you are right, the ones I am thinking about are Tusa, not Tekna.
 
I have SAS floating around inside the fog of my head somewhere

Do you all remember the ones with the round yokes, was that them.
 
SAS Good regulators, but some were made of stainless steel. That may seem like a good idea, but even stainless corrodes...and when it does it can be very difficult to separate the components.

BTW, I'm not confirming that the OP has an SAS, just a reply to @happy-diver 's post. Edit: Come to think of it, the SAS regulators I'm familiar with looked more like a Scubapro MK5 than a MK2

@Noomi SY Any regulator you can rebuild yourself is worth rebuilding. If you have to take it in to your LDS that is a totally different story.
