which atomic regs are these...

[diverintheflesh]

when the 2nd stage diaphragm broke, I replaced it with another that fit...


I don't know what model this is.


can anyone help?


it has no venturi, but it does have a cracking effort control knob.


on the first stage, swivel and environmental seal...


I know that there is only one first stage and one second stage service kit, so that can't help me identify them.


thanks.

It is a B1 first stage that has been updated to have the jet seat piston and sealed first stage. The second stage is a B1 as the inlet tube is Ti but has a Z2 purge cover and a frankenstein flow adjust. Get a proper B2 color kit and it will be a "real" B2 as it comes with knob and screw for the flow adjustment.

And if you remove the mouth piece there is a serial number under it. Call AA with that and the number from the first stage and they can give you a definite answer.
