[Boatanchors] Tektronix 10-10

I also have a DeVry Schools, Bell & Howell model 9516 Oscilloscope, built
many years ago and little used but stored wrapped, in a dry attic, for over
ten years.  It worked when stored but I would not dare plug it in now,
without doing a complete restoration of filter caps, etc.  It looks just
like a Heathkit and I'm pretty sure it actually is.  I have the
construction manuals also.

I recall that it is in excellent+ cosmetic condition.  Should someone want
it, you can pay shipping from 27516 or pick it up in Chapel Hill, NC.

I am looking for a dial mechanism I can use for a Regen receiver...some
kind of counter, like an old-fashioned National geared dial (with the paper
frequency chart & moving arm), or an HRO dial mechanism.  Or what
