It's an oven stabilized 1 MHz crystal frequency standard made by
Northern Engineering Laboratories of Burlington, Wisconsin (now defunct,
I think).   I would be willing to bet it has an entire oscillator
circuit and buffer amplifier on board.

"They are the arguments that kings have made for enslaving the people in
all ages of the world. You will find that all the arguments in favor of
king-craft were of this class; they always bestrode the necks of the
people, not that they wanted to do it, but because the people were
better off for being ridden."

Abraham Lincoln, July 10, 1858
