MTH Premier O gauge Chesapeake and Ohio M-1 turbine in original box, stock number 20-3042-1. 3-rail locomotive and tender show moderate run time and are C8. This has been upgraded to PS-3 and I am certain that it runs perfectly just like everything else in Leroys collection. Comes in an excellent original box with original paperwork, two traction tires and a bottle of smake fluid.
