Spectracom 8161 WWV receiver and reference oscillator

This is pretty cool.  This has a WWV receiver built in, and a disciplined oscillator.  There is also a phase comparator which also has a display printer. 

Beats the input to the reference, and shows the phase difference graphically on a chart.

Inside views as well as the outside.
