[Hallicrafters] Hallicrafters Calibrator

[Ken Kinyon - W7TS]

I recently acquired a piece of equipment about which I can not find any
information.
It is in a cabinet the size and design of a TO keyer.
It says only "The Hallicrafters Co.  Calibrator" on the center chrome strip.
it has an on off switch, a rca output jack, a selector switch, and  six
indicator lights for 1,5,10,25,50 and 100 Kilocycles.
It is solid state.
No other markings that I can find.
Can someone tell me more about it?
Regards,
Ken W7TS
