Neat work! What are the details of the induction coil?
I don`t have much information on it, it was supplied by the museum, I
shined it up and put my name on it.
22 pie shaped coils in series, about 8 inches long and 3 inches in
diametre. Driven by a light dimmer and a cap. I suddenly realize I`ve
forgotten most details of it, and I don`t keep records that I could
promise to check.

As for observing the tiny sparks I seem to remember that he was
pretty much in total darkness to see that. I've built similar but
much cruder apparatus working at a wavelength of about a meter but I
cheated and used a neon tube as the detector. The setup consisted
of a pair of rods with spherical spark gap at the center but no end
loading and with it and the neon tube detector it was easy to
demonstrate interference effects and reflections.
