I have been working on detailing three of these models to match Delaware & Hudson prototypes. I removed the cast on nibs with grabirons and lift rings, carved out the twin sealed beam headlights and replaced them with single Pyle headlamps, and lastly removed the two single horns and replaced them with 3-chime Nathans (I think).
Last on the list is to replace the cast on radiator fans with something more realistic. Do any of you know what manufacturer offers such a thing? I was unable to find anything specifically for this loco from Detail Associates, Details West or Cannon. Thanks for the help.
