PS this came from a Gould TC431 counter/timer, and pins 1-4 were connected,
but pin 5 wasn't,  So if anyone has a schematic for that counter/timer, then
at least part of the story could be clarified.

I have in my sticky mitts a Cathodeon Oscillator Type FS59 51/01 10.0MHz.
It might or might not be an OCXO.

Anyone know anything about these?   Five pins, the ones at the corners
marked 1 through 4, the fifth one either unmarked or the stamp didn't
register properly.   There's a trimmer access hole on the top.
