I bought a small pile of old scope probes partly because I suspected that in included a P410 or P510 probe (based on the pictures). I think that I have not been disappointed, but the probe has basically no livery of any kind. The only printing on the probe is on the cable ("AMPHENOL NO. 621-685") and at the back of the probe body ("ATTEN. 10X 600 V MAX. 10 MEG 14 ??F"). I think that means that this is a P510 (based on a PDF from TekWiki).
There's an empty, threaded hole in the probe body near the back. Is this where the ground lead is supposed to be attached?
