For Sale: A nice Rare pre-war Lionel 752W Union Pacific Aluminum M-100000 Streamliner set with the 752W Engine, the 753 Passenger Car and the 754 Observation Car. There are 2 vestibules included. The cars are in their original boxes. This O gauge set is from 1935-41. It had a working E-unit and whistle. The brushes have been cleaned in the motor and the whistle. The whistle impeller has been lubed. All the lighting is working. It looks like there has been some paint restoration on the engine and the grill has been painted black. The other cars may have been touched up in a few spots. There as some scratches and blemishes but for a vintage set, it looks good. It does need to run on O72 curves as it is quite long.
