Sounds like a solution a Mechanical Engineer would come up with!  Same kind of gadget is in my HP 8640B.

 

An Electrical Engineer would add a varactor diode (or just any diode) and a potentiometer.  Also, that would give

you the option to easily add a "huff and puff" type frequency stabilizer.  The old Eico would get actually useful.
