While we're on the subject of Emergency hopper designs, the article in the latest MM on N&W hoppers states that the N&W Class H-4 hoppers were "yet another design unique to the N&W." Peter Weiglin - If you're out there, this is not true.
It is correct if you want to be picky. The H-4 used the N&W-standard close-spaced Z-bar end braces rather than the lighter, wider-spaced angle section end braces of the standard design.
