Hickok Calibration Cell Needed

I am looking for the schematic/parts list for the newer zener diode calibration cell for my Hickok USM-118B and the WE version, as well, if they are different.

Thanks!

You may have already tried this, but I was able to find a lot of literature available on
my Hickok tube testers by Googling. I think that'd be your best bet if nobody here
can help.
