I know that I have further info re this large herald on Santa Fe's steam engines, but the quickest I came up with is from a photo in Worley's Iron Horses of the Santa Fe Trail, page 303. It shows a 3451 class Hudson with a single large herald on the tender, just behind the locomotive cab. The photo caption reads, "For a time Santa Fe applied a large company herald to several passenger locomotive tenders." The photo date is 1940.
I know also that at one time Scott Mann was considering a run of ATSF 4-6-4's among which was the double-herald tender paint scheme. I would've jumped at the chance, but, alas, as so often happens there were insufficient takers for this engine/class among all proposed paint schemes to proceed with the project. I believe the MTH Premier runs in about the same time frame had much to do with this stillborn effort. At least, that's my aging recollection.
But, yes, I'm am most sure that I've seen photo(s) of this tender herald as applied to the 1:1's. Surely, though you can judge that they were not easy for the paint shops to apply, the maintenance teams to keep as clean and proud as the top brass would have them be at the point of their crack passenger runs. Also, if the 1940 time frame is about right, I'm sure the war effort shortly thereafter had much to do with eliminating this bit of bling.
I'm sure others more knowledgeable will chime in......stay tunedl!
