Incomplete set. Considered for parts or repair. Untested, found as is. See pictures, Looks to be in pretty good shape (the track that is). A few of them seemed warped, but I am wondering if they are banked? There are 3 like that. I have not tested any of the equipment, one of the transformers doesn't match the name of the track. The box is worn out but could be used to make a new box. I imagine there arent many of these boxes floating around from 1966.  Any questions let me know, I bought this at a sale a couple weeks ago along with some other tracks. Pretty cool. I am not sure what the scale is, I just used similar listings, this is certainly the largest slot car track I have ever seen, the cars are much larger than hot wheels cars lol. Also, not sure if the cars fit but I found them in the same garage so I am sure someone will appreciate them. The plastic frame one slides to accommodate different bodies I assume which I thought was super cool.
