One matched pair of early 6922 tubes of Amperex PQ brand, by Amperex USA.

Featuring D-getter, gold pins, long tube body. D-getter tubes were only produced for two years after the invention in 1958.  After that, O-getter followed. Early tubes are more desirable for sound quality, but they are extremely rare to come by.
