Wouldn’t the BRHS be able to contact EMD, as they would have the records for the proper paint codes? Look at the recent NS “Heritage Fleet”. The NS talked to both EMD and GE for paint codes for these heritage units, the railroads that actually were customers of EMD and/or GE. About ½ of the railroads the NS crews had to “shoot from the hip” as some of the predecessor roads were neither EMD or GE customers. I am not trying to sound “off topic”, but just making a suggestion here……
As one of the remaining dinosaurs from the BRHS formative years, here is a bit of history concerning our roots. Both Rod (Bat) Masterson and Ed Derouin served as conduits to manufacturers to insure some tokin of accuracy in their models and paint colors. Sadly both of these friends are gone due to cancer and no new links have been established to fill the need. Another aid in matching Blackbird/Redbird schemes were the paint chips that Bob Landregan once provided, now probably very rare. Uncle Bob matched the original Duco color codes and had Dupont produce the actual color chips. When one was the chief engineer at FMC/Gunderson, such requests were honored by suppliers!
