I just got given two conshelf SE2 regs. Friends who dont dive any more.
I have 6 other conshelfs so quite familiar with the stable overall.
The first stages are SE2 with 3 x 1/2" ports (commonly know as PIA) + 1 HP
Two primary 2nd stages are standard SE2 plastic jobs
Its the plastic octopus second stages are different. By the SN stamped on them I think they are 1996?
They are 'Spiro Octopus' units - that look almost exactly like SE2s but not quite:
- Oval (not round) exhaust valve
- 2nd stage poppet has no screwdriver slot on the end - it has a square shank that fits the square slot in the body and prevents it turning
- Poppet nut is 'different' smaller size and thread to SE2 2nd stage (metric?) - NOT interchangeable with the standard US poppet.
I know Spiro/USD/Aqualung are all the same manufacturer and there have been endless tweaks to the models. Does anyone know anything about these? They are in great condition and i want to get a couple of service kits (mainly because I cant use standard poppet locknuts) but I dont even know what to look for. I can provide photos of the dismantled units if that will help. Ideas?
I have all the Aqualung parts diagrams but nothing specifically for Spiro. Are they available?
