I know someone here would like to know about what I just saw for sale but don't remember who.

Just a note:
A complete set has 30 tracks per side, these are worn in the tire guide area but would make a good static display. The tracks are a mix of the early and latter style of stampings. You could replace the worn tracks with new but it would cost about $2000.00 and change. Just for information.
