This exhibit is labeled within the John Lawrence Collection as a backward wave oscillator, which is a type of device related to the traveling wave tube amplifier in its operating principles.
Further information from Emilio Ciardiello establishes this exhibit as an external cavity reflex klystron. Working within an external cavity it would cover the range 7 to 11 GHz. It was used in the HP 620B signal generator. The 1950-004 was a second source for the Raytheon Qkk1315 which was itself a selection of the standard type 6390.
This oscillator produces about 60 mW of RF.
The thin glass tube envelope is 20 mm in diameter and, excluding the base pins, is 87 mm long.
