An interesting photo on this site is of CNW 128698, a double sheathed box
car from 1912. What I found odd was the dark lines or shadows spaced
along the side sheathing, making it look somewhat like the panels of a
steel sheathed car. What is it in the design that gives this appearance?

Rob, it appears that the vertical wooden posts of the side framing were
exposed, with the sheathing fitted between them and the surface of the
posts standing out slightly farther than the sheathing. The diagonals
would have been concealed inside the sheathing. Note the bolts that
secured the vertical posts to the side sill.
