I have heard about these drives now for a few decades and yet have seen nothing about them other than being installed in large UP engines, U50Cs and DD40s. I have now seen on Ebay this last month a couple of these Overland U 50s selling for near and over 1,000 much more than the $695 I paid for mine. The latest one seen is unpainted and missing a hatch door and still selling for $950+ but it has this mentioned Doug Cockerham custom drive. What is this drive and are they still available as I have 2 of these U50Cs and neither has the custom drive but both are painted and weathered making nice viewing pieces.
Phill.
