Re: RGS 20.

I did artwork for an RGS sunrise herald for Bill Lund's 455 trip back in 1997, and revised it a bit for RGS 74 when it was being prepped to go to the museum in 2011 (before the authorities in Boulder understood what they had apparently agreed to). There are substantial variations for the different locomotives, particularly between #20 and the others, but it looked like you nailed it for how it looked on #20. Several letters are very different, and the lower part was off-center on #74 and #455 but not on #20. This is a piece of one of Jeff's photos with a matching piece from a 1949 photo taken by B. F. Cutler in Durango (the 1949 image was adjusted slightly to match the perspective of Jeff's photo):


Here's my 1997 version for RGS 455 as applied to D&RGW 463's tender, which may not be as accurate as the one on #20, but I think the differences between them are mostly historic, based on the differences in the original heralds:


And my 2011 version on #74's tender:


This photo of #74 was taken by B. F. Cutler in Durango in 1949, probably the same day he took the one of #20:
