I just measured my F&C model #6770 and it is the correct height as compared to the prototype schematic in the Freight Car Equipment of the C&O Railway, August 1, 1937. They were built in 1930 and ran through the 60s. I reason that I bought the kit was because they are a bit shorter in height than most automobile boxcars and give the consist and different look. We don’t want all 10’4” 40’ auto boxcars do we?
