You are looking at 8-Aurora T-jet SOLID & OPEN RIVET Slot Car Chassis HO scale. They are in used condition and show wear. Missing some parts. Transformer tested and 5 did run and 3 did not. Pictures 2 thru 7 are the ones that did not run. All should be cleaned and oiled to run better. Might need new tires and brushes. Please check pictures to see condition and what you get.
