I picked these up at a yard sale with some track about ten years ago. I don't have a power supply or any ambition to set them up yet, but they're cool. 1/24 scale.
What you have are 2 revell kits. The ferrari 250 gto, and the light blue car, looks like it may be a chapparal. These are very valuable to collectors, the other car looks like a lexan body, dunno the manufacturer. I wouldent race these, as the plastic and lexan is probably very brittle by now. Make grest shelf queens for the collector of vintage slot car stuff tho. My best guess on age on these would be mid 1960s , prob 1965.
