Jerry and John,
At the risk of being labeled one of those obnoxious "rivet-counters", I find it interesting that most models and modelers put the larger numbers, typical of the "Flying Rio Grande" schemes, on the back of tenders painted in the "herald" schemes. As far as I can tell, this is wrong--they should have the small numbers. I don't know why this is perpetuated, but apparently it is. It is also probably a partial basis for the belief that restored prototypes should have the larger numbers.
