Who else wants their old toys back?

I also remember in pre-school (yes pre-school) someone had donated an educational interactive traffic light controller set.

It had 1/25 (maybe 18th) scale cars in several different models, but I only remember the 63/64 impala.
They were metal, with white interiors, and a fair amount of detail.
They also had a heavy, flat metal plate on the bottom.

Also in the set was a four way intersection, with a traffic light.
It must have been about 3 feet square.

When you put the cars on it and approached the light, it changed and went through the G/Y/R sequence.

I can only assume it was made as a driver's ED aid, to show activation and light timing, and to caution against "stale" lights.

I loved that thing, and I remember they rarely had it out. I remember asking for it specifically several times, as I figured out where they kept it.
