The above tanks are military surplus. Valves are CGA 540 with 3/4 npt threaded boss. The R (positive reserve) manifold is quite rare.

I don't know any info about Superior. Possibly they made oxygen valves, because their valve looks very much like one.
Healthways advertised the Superior, post type K valve as a "medical" valve.
