I second OH, in particular Larry's roster provides a valuable resource for those of us with these particular cars "in the queue" who may want something else besides another PRR X43C and aren't afraid to cut into one.
Likewise agree with Ed that the contribution of the 70's Roco car(s) to the shrinking scale 1/48 world then was indeed an event worth recognizing, that variations of these cars persist today says it all too. IMO ditto the G43
Well done gents.
