Dave,
I think that your explanations as to the delay in re-lettering the inherited C&S freight cars is well thought out and makes sense.
But there are a couple of other likely explanations. Certain types of cars were already scheduled for major shopping. Darrell Poole, in an old
Outdoor Railroader article, chronicled the rebuilding of the 26' and 27' Tiffany reefers in 1902-1903. Derrell found documentation that as early as 1900, C&S management knew the Tiffany's were worn out and produced authorization for their rebuilding "when funds allow". A few of the cars in the best shape were re-lettered before the shopping, but since the rebuilding included a complete replacement of the exterior sheathing, it made no sense to re-letter the majority of the cars prior to shopping. So they trudged on with their UP lettering in what ever light color they were, until the rebuilding occurred. Photos of the 1901 Washington Spur wreck and the Riverview wreck of spring 1902 show them with light sides and UP (DL&G) lettering.
Management may have already allocated quite a few of the 24', 26' and 27' boxcars to be converted to outfit cars. Re-lettering may have waited until the actual conversion occurred.
Finally, just because cars are listed as still in their UPD&G/DL&G numbers in the ORERs, doesn't mean that they are in actual everyday use. In the case of the inherited coal cars, management was already preparing for the 1902 (phase 1) coal car building program, which would make the older cars, <30 foot in length, obsolete. Such cars, in the worst shape, may have been slowly moved over the months, and set out on weed grown sidings in Denver or Como, where they sat until stricken from the roster and scrapped.
Anyways, thanks to all for your thoughtful replies to my query. My three 27 foot cars are complete, detailed to my satisfaction and ready for the priming and painting:
These three cars will receive C&S lettering. But I still have a few more kits stashed away in the Sn3 closet. At least one will emerge heavily weathered with DL&G (Union Pacific) reporting marks and numbers . . .
