Eldon Slot Cars and road Race Sets

The first slot car sets of this design were produced by "Ungar";  either Eldon bought out the design or the company name was changed to Eldon, we are researching this.

The early Ungar sets were battery powered and had the same track that the Eldon brand would use for the production run.  I have seen some Eldon sets that had track labled Ungar.
