HICKOK 209A HUGE dial VTVM calibration data/help needed.

I don't mean to hijack your thread, but I have an earlier 209A, made when the normally silver parts of the case and dial were black.

It is very similar to this one on Radiola Guy's website:

I'm never started rebuilding mine, as I cannot figure out how to get the AC probe apart to check the 6AL5 and the associated circuitry.

Unlike the later silver ones, and Radiola Guy's picture, my probe is all black and looks like it is cemented together. Any ideas?
