So, did they actually have most of the tubes already? I can't imagine them finding such a quantity of some of them.

I too donated some dekatrons, but because I live only an hour away I used the donation as an excuse to go see the WITCH in person :) This was 2+ years ago, and the machine was very definitely non-functional due to power supply problems. I spent a very happy couple of hours there chatting to the chap heading the restoration, sharing some dekatron knowhow and taking photos. At that time they were very approachable, grateful for the tubes & input etc. If I remember the blog entries correctly, the team had significant changes in personnel due to illness. Perhaps they dropped the ball in the changeover with respect to thanking others who were generous with their tubes... It is just the most amazing device, and I'm impressed that they've managed to save it. BTW, you'll notice that there are a mixture of orange and purple dekatrons shown in the video - these are GC10B and GC10A respectively. They've deliberately replaced some of the GC10A with GC10B because the glow is much more visible for public display. The design does have one or two selector dekatrons also in control circuits, but the vast majority of the tubes are just counters.
