These sets were part of a case that would have been sent to a store. They were all originally in bags but the bags disintegrated so badly that only five remain. All of the cars are 2.5″ long. It is interesting that the are several quality control misses with these sets. There are several cars that have at least one wheel attached backwards and one of the cars has the hitching rod installed over the axel rod, leaving it loose.
From my private collection.
