Hi. ALCO PA’s got a paint change in the late fifties I believe from Daylight colors to “Lark” dark Gray and bloody nose. Does anyone know how the PA-B unit was painted? Was it also “Lark” dark gray? Was Southern Pacific also painted on the sides like the PA-1 lead unit was? I have been online all over and could not find any photos of the B unit from that time. Any help from you prototype guys would be appriciated. Thank you.
