If you have a 7-1942 or 10-1942 ORER I would be very grateful if you could look up UP 961100-961199 and share the the car count and inside height. This was a small series of 4 cars that originated in 4-1942 and vacated 10 and 11-1942. The series does not appear in the 4-1942 ORER. They may have been the first of the "bomber boxes" on the UP, hence the curiosity about the inside height reported. All 4 cars were class A-50-15 and renumbered into 561100-561199 (40 cars) which did have an inside height of 12-4 for Boeing B-17 wings.
