Scott,
This is not an authoritative answer to your questions, but I'm confident that my answers are generally true.
> 1. Does the C&TS or the Friends have any interest in the aquisition of original D&RGW equipment?
Yes. However... preservation and maintenance of the existing equipment and facilities is the first priority.
> 2. Is there any equipment out there that would be available for aquisition by the C&TS?
Yes and no. There's lot's of stuff out there, but the folks that have it aren't in any hurry to part with it. Worthwhile stuff becomes available only on rare occaisons.
> Would anyone like Knotts or elsewhere that has or uses D&RGW/RGS equipment consider trades for C&TS steel coaches?
Probably not... unless there was something they really wanted in the bargain.
