Steve - can you say where to find that collection?

FWIW, there is a photo of CMO 1720 in the Vancouver collection of Bill Lane photos. It has a seven panel Superior door with the placard board on the second batten down from the top. The view is slightly upwards and shows, sort of, the brake platform and running board.
Dan & Eric,
Sorry for being late to this discussion. Today I contacted Jeff Koeller, who I consider an extremely thorough source on steam-era CNW/CMO freight cars. Jeff provided the following information that pertains to the 200 CMO steel rebuilds numbered 37100-37498 (even numbers only) rebuilt in 1941-1942, then received some rehabilitation in 1954 when 187 remaining cars were renumbered 1658-1844 and painted green & yellow.
When rebuilt, all 200 cars received Universal hand brakes, U.S. Gypsum running boards & brake steps of the expanded metal type, and retained Andrews trucks. The doors were split with 100 each of two types:
1941 cars - CMO 37100-37298 (even) - Superior doors (7-panel design).
1942 cars - CMO 37300-37498 (even) - Youngstown doors.
In my conversation with Jeff, I did not ask for the specific renumbered car numbers that received Youngstown doors vs. Superior doors. That would involve looking at each CNW car card that have “old” and “new” car numbers. Any new 1954 car number with an old car number 39100-39298 (even) would have Superior doors. Similarly, old car numbers 39300-39498 (even) would have Youngstown doors.
Photos in Pat Wider’s RP CYC Volume 23 article on steel rebuilds of double-sheathed USRA box cars include CMO 1682 & 1808 that received Superior doors. Whereas CMO 1672 & 1720 had Youngstown doors. It’s thus apparent that the 1954 renumbering was not in the same original car number sequence.
Another detail to be aware of are differences in the riveted sides sheets. Photos of 1682 & 1720 with Superior doors rebuilt in 1941 show four essentially-equal side sheets on both sides of the door (i.e., 8-panel sides). Photos of 1942 rebuilt cars with Youngstown doors 1672 & 1720 show an unusual version of a 10-panel side arrangement in which two essentially-equal side sheets nearest the door comprised the same width as one sheet of the 1941 rebuilds, which for this I’ll use the term “half-panels” that Jeff thought was a descriptive term. In Jeff’s research, he indicated that the last 60 CMO cars having Youngstown doors (37380-37498, even) had this unusual side arrangement.
Thanks much to Jeff Koeller for sharing this information that he had spent considerable time researching.
Lastly, once upon a time was an overhead photo of CMO 1682 on eBay in which the U.S. Gypsum running board received yellow paint but with some black car cement overspray at the ends. A color photo available from Bob’s Photo provides a ground view of CMO 1672 also revealing yellow along most of the running board edge but some black overspray at the ends.
Hope this helps.
