Actually there have been at least two C-46s on the US airshow circuit; both belonged to the (then) Confederate Air Force, “Tinker Belle” which was based at Big Spring, Texas, and “China Doll” which iirc flew from California…not sure whether either is still operational though.
BTW, on History Television in Canada is a documentary/reality series called Ice Pilots NWT, centred on the Arctic operations of Buffalo Airways who operate DC-3s, C-46s and C-54s; among the C-46s seen is C-FAVO which I posted on the other thread. There’s some really fine flying footage in that series.
