Interesting piece of hardware!  Some Googling suggests that one was used in a quantum magnetometer (an experimental one, at that) back in the mid-1960s.  That might explain why it doesn't have a traditional lock-in loop.

I don't see any references to the model number in Bill Riley's book, but he does cite an early-60s Varian patent for a device that looks a lot like it.  This patent does describe a complete Rb frequency standard.  No schematics, unfortunately.

Thanks KE5FX.
These were used by Varian to make an Automatic Standard Magnetic Observatory
(ASMO).
