MIDNIGHT VINTAGE SIERRA XR4I SLOT RACING SET,This was made in Hong Kong in the early 80s before the Sierra Cosworth was released.it is in quite good condition for it's age and I think it's complete,it hasn't been used for some time,but I put a battery on the cars and they both  still .work,The cars are about 4 inches long,so it is a bit smaller than a Scalextric and battery operated only,it will need four D type batteries.
