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. Regards Paul WB8TSL
