Untouched original 1548 windup passenger set from 1936-37. Cars show some scratching and a few light rust spots here and there, they couple together properly. Engine is missing the spring and sound unit, the large gear does operate the wheels. I do not see any pot metal issues, the rear lower body corners are a little bent but not cracked. The track is original and looks nice for being almost 90 years old, does need some straightening. I added the key but do not know it’s age, it has some light rust showing on the edges. I have provided plenty of pictures to show the details.
