Can you help direct me to the series these and the 4 board gons were in on the D&H? I model 1930, and these may have remained in service. There were 550 32' 30T single hopper gons still in series 100-601 and 10000-10499, all with a 4' IH. Do you know if these are a match?
FWIW, a pretty good looking as-built D&H Seley was shown in one of Eric Hansmann's blog posts. It was done in CAD in HO; I just inquired about a possible rescale to S as those would be more common in my era of interest. Would those be too new for you?
