First off, none of the 480's today have their original whistles. As built the 480's had single note "hoots" like 463 wears. Back then the D&RGW practice was freight engines had hoots, passenger engines had 3 or 5 chimes. By the 1930's this was done away with, and whistles got changed around. Your picture of the 482 shows pretty much "as built" with a hoot whistle and the factory lettering. The lettering style BLW applied was essentially the SG style. The cab numbers are larger that was standard practice on the NG power. Likewise, the tender lettering was larger than that used on NG power. For what it is worth the lettering style that was used from the mid-1970's to the early1990's was based on this lettering. When 484 was scraped down and repainted and lettered in 1976 by Ernie Robart, he found the original lettering and copied it.

Sorry about the derailed thread here....

The whistle that was on 489 in 1981, is mine. It is an ALCO 5-chime. It came from a big burly 0-6-0 that was owned by the Phelps-Dodge Corporation and was used in the pit as well as a switcher in their big copper mine in Ajo, AZ. The whistle lived on a couple of other C&TS engines also. Now it lives in my garage....
