My pie-in-the-sky wish is for a 1500-class Frisco Mountain; either the 1522 or one of the slightly earlier ones, like 1501.
Lionel's probably as close as your going to get with their latest 4-8-2 offering:
And yes, the air horns are prototypical as built:
Rusty
Air horn fit was dependent upon assignment: some territories required them; others did not.
Anyway, the 1500s were not USRA, and they differed quite a bit. They were better engines all around.
The Lionel catalog pic suggests the red will be too bright, the black will be too dull (the Frisco kept their engines Williams shiny), and the white walls are an offense to the soul.
You may be right in that this would be as close as I'll ever get, but, if I am going to lay down more for a toy than I paid for most of the cars I have owned, I want it to be RIGHT. I am not worried about every last detail, but I want the shape and the paint to be right.
Still, I had not seen this offering, and I appreciate very much you pointing it out to me. Would that it were correct!
This concern, of course, is not one I have to worry about with the #333 ;-)
