I think all the old hp 100-series frequency standards were
tube based. Even the 100 kc crystal was mounted inside a
conventional vacuum tube. The old GR quartz standards had
tubes: http://www.leapsecond.com/museum/gr1103a/
So these would make a nice companion to that all tube nixie
tube clock.

The model hp 101A was hp's first "transistorized" standard;
after that came the 103 104 106 107 105 105-44 108-11
