[time-nuts] Spark timer.

[paul swed]

Peter will believe we both have purchased items from the same person at
MIT. Always has interesting bits of old gear. I did indeed pick up a
gen-rad tuning fork reference/standard at MIT Type 723 c and 1000 hertz. It
works well and cleaned up even better.
If I had seen the item you picked I will bet I would have been clueless to
what it was. He has odd things after all.
Enjoy.
