This is a lot of Monogram/Revell 1:32 scale slot car model kits and parts.  It appears to include numerous car bodies, chassis, parts, and hardware to assemble various cars.  Parts all appear to be NOS new old stock, never used.  Three cars/chassis have motors, all were tested with a 9v battery and operated fine.  Two NOS motors, tested operating fine.   Some or all items may or may not be factory "back door" production samples or mockups.
