Thanks for the reply, Tbar, but I was looking for a schematic for the A.I.R. 1 regulator, not the A.I.R. 2 Gen 1 BC inflation device. I did get a good A.I.R. 1 schematic copy and an annotated Scubapro O-ring chart from another diver. I also have an 8-page set of instructions for the reg from another diver. My original request has been fulfilled.

With the data I received, and what I could learn from all the experts and helpful posts, I made some tools; disassembled both AIR 1's; inspected and cleaned the internals; and reassembled/tuned them. Both check out OK, and are ready to go. First stages are MK 10's. Plan to dive them this weekend (with my trusty G250 as a back-up) over at the channel islands. I also made a couple of the p/n 11-126-130 "regulator storage keys" that engage in the purge button slot and depress the back-up-disk/diaphragm to lift the poppet off the orifice and relieve the so-called "engraving" of the poppet seat. If I don't kill myself, and all goes well on this coming Sunday, next week I'll post how they performed .

I do store my 109/156 with purge depressors, but I avoid using them on my converted pilots (metal Air1s). The valve of the Air1 is the same as the D-series which does not incorporate a storage relief for that valve. With the difficulty of finding replacement diaphragms/exhaust valves for the Air1, I would avoid any additional stress on that part. The light spring in the coaxial valve design makes it pretty unnecessary. I suspect Scubapro included the key in the Air1 design as a carry-over from the 109 design (very strong spring) and determined it was unnecessary by the time they introduced the D-series.
 
Made 3 dives with my daughter on the back-side of Anacapa Island yesterday. Alternately used the AIR 1 and the G250 to see how they compared. Both seemed to breathe about the same. The AIR 1 was different (mostly, I think, because I am less familiar with it.) I'll probably set it up as my primary for a while and see how I like it over time.

Again, thanks to all who supported with info, helpful posts on SB, etc.
