This thought was prompted a bit by an rather old Model Railroader I found while out thrifting, specifically the article The boxcar fleet of the Fifties by John Nehrich in the March 1986 issue. While WW2 & post WW2 era steel cars seem well represented on average in O Scale, I must confess I was rather taken with the idea of mixing in a few older, shorter cars of the 36 ft wooden variety, as well as curious about outside steel braced and early steel cars like the PRR's X29 (mentioned specifically in the article). Obviously, these sorts of prototypes are rather few & far between in the O Scale world, but I'm curious: does anybody try and run some of these earlier boxcar designs on their layouts already, and what rolling stock is out there already?
The only wood cars I could think of in O Scale were woodside refers, which represent cars of the 1920s, and the trussrod 34ft boxcars from MTH. I'd kind of be curious how the later look next to more modern cars, as they are close (but not quite) to the turn of the century cars that would have been the oldest examples on the rails in the '50s (but still earning there keep, for example 50% of the D&H's boxcars were 36 ft in 1950).
