I recently came into possesion of a set of older Poseidon regs and was hoping to get a bit of insight on their condition. Unfortuantly I am not too familar with poseidon regs so any help would be much appreciated. I will also try my best to answer any questions. Again, for anyone taking the time to help, thank you.
Attached is a google drive folder with pictures I figured would be relevant in diagnosing them.

I recently came into possession of a set of older Poseidon regs and was hoping to get a bit of insight on their condition.
I assume, also being unable to see the images, that you have either 2960 (Odin) or 3960 (Jetstream) first stages, and not the MK3 or Xstream?
Regardless of what many have to say, Poseidon regulators are quite straightforward to service and to tune -- provided that the manuals are followed and everything, especially in the 1st stage, is kept scrupulously clean. It is quite simple to trash a seat; though I have worked on them for years, without any issue.
An all-too common problem with used Jetstreams, however, is damage to the servo valve, the "needled screw-on cap" at the very tip of the second stage. If that is the case, it or they will have to be replaced. Once bent, they cannot be straightened; though I have now been told otherwise by some in the know -- but would not be approved by Poseidon.
Parts, though increasingly pricey, are now readily available over the counter in the US and Europe, even for regulator models that haven't been produced for thirty-plus years; and I wouldn't think twice about using any of those older models as primaries at any depth, which were all very well made and well-nigh bulletproof.
My current pony bottle is fitted with a Cyklon 300 from the mid 1970s, which still breathes beautifully, and I commonly use the Jetstream with either the 2960 or MK3 for rough surf entries . . .
