American Flyer Prewar Streamliner 1621C O Guage NR

Hello, this is a prewar A.C. Gilbert American Flyer Streamliner. I got this from an estate sale. The engine is a 1680 and come with the tender. There are 4 cars. One car has a lot of pitting on one side. It is missing one axle on one of the trucks. There are three axles on each truck. The cars are 1621 C and the end coach is a 1622 C. two of the coaches have some slight pitting, but still nice. The end coach is very nice. I hooked the engine up to a transformer and it would hum and try and move but would not go. I have some boxes for the cars and tender. The boxes are rough. If you would like additional pictures let me know. Thanks Robert
