Dad brought home a bombardier's control panel. He had a transformer to power it so all the lights and motors worked. It was about the size of a pinball table. It had four columns of amber lights, representing bombs I think. There were servo switches and glow-in-the-dark switches and a pair of rotating bars to indicate whether the bomb bay doors were open or closed. I suppose it would not be good to release the bombs with the doors closed!

We've never found a photo of the whole thing but at the bottom was one of these things:
