This is a beautiful Rivarossi Challenger, 4-6-6-4, still in perfect condition. it is made by Rivarossi, and marketed by AHM. I listed it as new, because I bought it as new, and looking at it, though I am not the origional owner I am convinced that this is the case. I have tested it on a short piece of track and it does run forward and reverse. It comes in its origional box witch is a little rough, and has origional paperwork.
