Amazon lists brass insert knobs from "Essentra Components (formerly
Reid Supply)".

I buy a lot from Amazon to minimize the exposure of my credit card.
They seems more like a flea market selling closeouts and overruns than
a reliable long-term supplier. Several items I bought are no longer
available and the parameters of electronic components suggest they
came from the out-of-spec bins on the tester, for example a batch of
75V gas discharge tubes measured either less than 70V or more than
80V. 50V Schottky diodes from them have PRVs in the high 40's, none
over 50.0V at 50uA leakage.

I recently tested an old Radio Shack "25A 50V" rectifier bridge. The
number on the part corresponded to 600V PRV and it tested over 900V.
Maybe a good one snuck in by accident?
