I am assembling a Branchline kit of a Monon 40' Boxcar with the National B1 trucks and 7 panel Superior doors. I came across a photo of a car from 1958 from the same series that had "C.I.L." reporting marks. However, my car represents the car after Monon repainted them in the late 1960's. Were reporting marks on the 9100-94XX boxcars changed to "MON" after the repaints or did they remain "CIL" cars?
