CLW has both versions of the Hodge truck, and the kit comes with a spoked 45" wheelset. Some assembly required.
The Southern PS-4 used both 4 wheel and 6 wheel trucks. The 6-wheel trucks were Commonwealth, not Buckeye.
Bob - with that information I could also buy a wheel set and repair the one I have. It should be a simple soldering job to fix, but an upgraded version sure would look nice. Of course that leads to the slippery slope of upgrading other parts of the loco . Also thank for the information on the tender trucks. I'll have to do more research.
