Hi Bob, all
Here’s a shot of ours at Worcester ATC, 1976. I restored it using the best from two wrecks we had, in-between dealing with the Javelin outside. I left in the early 80s and know nothing more than it was gone shortly afterwards. I remember using a GPO uniselector to allow a multitude of signals to be sent to the cockpit, via the limited number of still-working sliprings. The bellows were poor, but we had a tremendous time with it for a short period. The crab trundled off the chart table a few times, I gave it a bungee-based safety harness after it bent its ink-laying wheel!
