Lionel Prewar O Gauge AMC Special Set #1 w/ Boxed, Nice. AMC Store Specials are difficult to find. Loco runs, frame is straight not repaired. We are aware the engine should be a 257 and I have one if you need it. However we received it with a 258 so left it as found or as received. The Photos Are The Description.
