Love your kitbash of the Milw 713526 car. I model the Sierra in 1955 and have conductors lists from 1952 that show Milw 713916 on the Sierra. I also have an Accurail kit to make into a Milw car. Your kitbash inspired me to dig it out and review a new parts list and start on the project. Thank you for your posting.
