Hi All: I have an HO scale Kato undec RS-2 w/water cooled stack that I'm going to be turning into a Frisco "pure Alco" unit. I need a few answers about available HO detail parts before I start trying to gather up stuff. (I've been away from HO for so long, I am not conversant with what is available.) * Horn: I'll make an assumption that Frisco's two "pure Alco's" that escaped repowering until late 1960 had 5 chime horns (bells forward)? If so, is the old Cal-Scale 5 chime about the only game in town in HO? (I have a couple/three of those on hand, I think.) * Nose corner number boards: I saw pics here of someone's HO model of #553... and it had the number boards on the nose corners. Who makes them, and what part # am I after? * Class Lights: Same question... who makes class lights that are appropriate for the Frisco RS-2's? Any other suggestions for needed details found on the Frisco RS-2's? Thanks for any input!
