WTB: Tek P6109 probe adjustment tool

I have an old Tek T922 scope with two P6109 probes. The scope works
good enough for the little I use it but the traces are not complete
(peaks missing in some cases). From what I understand, if I could use
this special tool then I could adjust the probes and possibly make the
situation better.

Looked all over but of course I can't find the tool. I don't know why
they wouldn't make the adjustment via a slotted screw (I guess so they
can sell probe adjustment tools).

If anyone has one or knows of a place that stocks it please let me
know. My googling has failed.

Thanks.
