I went to the HackGreen hamfest today.
Small, in an MoD "farm shed", the usual traders I see were absent (probably too far for them). Not much new stuff, lots of old stuff, so relatively interesting.
I picked up three Philips ZM1050 decatron-like indicators

and an APC UPS, shown with a working front panel .
The adjacent "Secret Bunker" museum was well worth a visit. It would have been one of the regional centres of government if WW3 had started. Now it contains some interesting exhibits I haven't seen elsewhere e.g. Russian equipment, missile warheads and payloads and a WE177 400kt bomb. The WE177 and payloads were both surprisingly small, and I can see how the concept of a man-portable nuke-in-a-backpack is technically feasible.
