Regarding the outside-braced reefers, there is a nice color photo on p.78 of Lavalee's "NG Railways of Canada" of the author himself posing with editor Ritchie in front of two reefers in this class (no. 330 plus another indecipherable) in CN lettering, June 24th, 1952.
Observations:
- in the b&w 1945 photo of reefer 325 (2nd post in this thread), the car sides are so smooth and glossy that it looks like sheet metal siding (photo is a notch overexposed). But the 1952 photo clearly shows horizontal wood siding.
- the reefers in 1952 appear to be light green color, in direct contrast to several yellow-painted structures in the photo background. However, the ladder rungs, and the toe-kick splotches just above them, seem to show a lighter yellow color. It's possible that the "light green" reefers in the 1952 photo are actually extremely-sooty yellow. [ Interesting that in the only 2 photos I've seen of this car class, one is completely unblemished, and the other is highly weathered... either way, too exaggerated/implausible to seem "realistic" on a model railroad
]
- boxcar variants of this outside-braced type with sliding doors are pictured in Lavalee p.53 (b&w 1942 middle & much later CN era bottom), p.66 (color, middle pic circa 1950s), p.68 (1952 color, background of top, nice view on bottom), p.82 (lettered for shortline AND Co.). Color is brownish "boxcar-red" in the 1950s color shots. The "Newfoundland Long Lines" Youtube color film shows a boxcar of this class in the wartime/Newfoundland era at 06:30, painted in a much "redder" red.
- from Ralph's notes on reefer 325 (2nd post above) and the fresh-looking 1942 photo of boxcar 2366 (Lavalee p.53), it seems that these outside-frame wood cars were wartime acquisitions for the Newfoundland.
