Steve-
A quick look at the 1955 OER (thank you Al Westerfield for the handy CD
format!!!) turned up NO flats for the C&S and only a handful for the FW&D.
The FW&D were wood racks and for plasterboard service. The dimensions
suggest it might be the bulkhead version of the FM14. I don't have any
equipment
diagrams handy to see if they were Q design or something funky.

If the CB& Q had these cars, do you know if the C&S or FW&D also had them.

I would be interested in diagrams and will have to see if I have the #15
Bulletin.
