C&O Heavy Mountain?

[skipgear]

Will we see any more of these? The C&O version was very unique and probably the reason they are sold out. It has many details that are needed to create other mountains. I wouldn't mind another number or two for C&O also. The undec w/vc16 tender doesn't have the valve gear, cab or trailing truck that the full C&O version has so I can't just buy the undec and make more C&O's.
