I think it would be fair to say that the decission, in 1949, to back date the No.9 and add the "goofy" stack and color had nothing to do with historic preservation. I read a lot of posts and hear a lot of opinions that this was done as a slap in the face to preservation. Well, I think it is safe to say that in 1949 railroads were not trying to save steam, but rater get rid of it as fast as they could. I think it would be safe to also say that if it were not for the decission to send No.9 to these exhibitions, she may not have survived the scrapper. Hollywood has a long history of back-dating engines to make them look older, and the wooden pilot, diamond stack or "goofy" colors is what the public perception is of locomotives from the 1880's....well, I suppose it is "actually" what engines from the 1880's looked like...check out the E&P No.4!
I for one am VERY glad that the No.9 was choosen to be faked up and saved.
