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. The design was an AAR composite Emergency design that was also constructed for the Missouri Pacific Lines (MP 63000-64199; I-GN 65000-65099; Mo-Ill 6200-6249; St.LB&M 65250-65499) and the Midland Valley (9000-9024), all AC&F Lot 2605, built 1943-1944.
Quite true, but pointing out errors in MM is probably pointless, as Hundman's long standing practice has been to treat corrections with glacial indifference unless confronted about them, in which case he simply denies that the errors are errors.
