Found an ancient flyback transformer, with "ET 104 something" stamped on it. It might have come out of an early GE set, but not sure. If anyone can use it, yours for shipping. I don't know if it's good or not.

It looks a bit like the flys that were used in the 630 chassis sets.

Looks a LOT like a 630 type, which I'm looking for (actually, a fly-1 or compatible or Maggie #3200025-1). I'll take it :)
