The article describes and illustrates the design of nearly 9,500 riveted-steel cars built from 1937 to 1957 for six railroads including B&O, CRP/CNJ, LV, RDG, WAB, and WM. Included is a comprehensive roster of cars. While not discussed in the article, it was learned after publication that the Wellsville, Addison & Galeton (WAG) obtained a single car (car no. 3000) from B&O in 1957 followed by seven more (3001-3007) sometime between 4/61 and 7/62.
On page 54 the caption uses the word "removed" whereas a better choice of words is "lowered" to the full-open position.
