I have a used MTH challenger in the Clinchfield livery with original box for sale . It has the MTH Proto 2 control system in it. The smoke unit works but needs to be re-wicked and the loco and tender is dusty . Comes with 2 drawbars between the loco and tender. One is the original and the other is shorter. I didn’t like the large gap that came in its original form so I made a shorter one. I’d like to get $750.00 for it plus shipping. Make me an offer.
