This question was posted on the Steam Era Freight Cars list, and so far he's
gotten no responses. Thought I'd see what you folks might have to say:
"While preparing to model five F&C 1929 CPR mini-boxcars, I have been looking at
plans (via CP SIG) and multiple photos of these cars and have begun to question
F&Cs roof design.
The F&C car roof (Murphy radial all-steel) does indeed follow the design of the
plans published in the Nov. 1993 Mainline Modeler article, as well as CPRs own
designs found in CP SIG's archives, but photos of the car (where the roof can be
seen) do not show any evidence of stiffeners? or seams (a ridge) mid panel.
It is interesting to note that F&C uses the same design roof on their CPR 1932
AAR car while Sunshine's roof (same car) has no ridge line in the middle of the
panels of their Murphy radial all-steel roof.
Is it possible that some builders of the 1929 mini-box did not use the exact
roof design shown on CPRs own mechanical prints? Does anyone have a good photo
of a mini-box roof.
Thanks,
Jonathan"
