The QSK model used a Jennings RJ-1A/26S and I have seen a few supposedly
original Kilovac versions.
Dont know about the ZB but Denny Had demonstrated a LK-500ZC at Dayton in
(1987 I believe) in QSK mode for the complete show. It was keyed at up to
50WPM and the waveforms were displayed on a Tek 465A scope. Not once did
it appear to hot switch.
There were some differences in the switching between and even during
models....I doubt if a complete and accurate set of schematics exist!
