BOTH CARS HAVE AUTOMATIC BOX COUPLERS
One car tries to work, car on the left in 1st picture. Doesn't have enough power to dump. This car also has the early style of box couplers and early fibre board flying shoe trucks. This car needs rewired, wires are dry rotted. The bakelite motor casing has a break on one side.
The other car does try to work but you can barely hear it. This one has good wiring. This car is rubber stamped 3659 on the frame. This car is in very good to excellent condition otherwise.
Neither one has rust on the frames or dump beds. Both have flying shoe trucks. The wheels need cleaned up a bit. Very little paint loss. Clean cars. Message me with any questions, thanks for looking!
