Yes, another repeated error.
The C&C #5 passenger caboose story goes with the fact the number "5" could easily be seen above the one end door. The roster prepared by Jerry Best and Fred Stindt for the little Jhon B. Hundgerford booklet does not fall into this trap -- it listed the car without a number but notes its use at Millers on the T&G.
But there were those who thought that the number 5 was a Tonapah number. Then as paint begain falling off the carbody the thicker paint of the "2" on the side became appearant. This number matches a construction record book in the collection of Nevada Historical Society.
Then in time the photo below showed up. It is from a private collection, but I've used it both in a prsentation at Nevada State RR Museum and in an issue of the SPNG society's publication.
Notice that the narrow gauge car is up on standard gauge arch bar trucks.
