The "AIRFLO" a DIN wannabe I guess. If you down load the 70 Healthways catalog, it is in it. The gauge was a an additional $12.....a $13 value according to the ad.

Later in the catalog, there is an optional yoke adapter and it discusses the new Healthways valves all coming threaded to accomidate both the Airflo and standard yoke regs. I would like to play with one but so far the ones of these that have come up on ebay are more expensive than I care to play with. A have yet to see one of the threaded valves so even if you find an Airflo, you still need to find one of the valves.....still, a toy I would like to play with some day.
