I am trying to narrow down when two groups of Fruit Growers Express steel rebuilds first appeared in the ORER. Here is what I know about each.
FGEX 10850-10999 appeared by July 1937 and was not in the July 1936 ORER entry. If you have an ORER between these two dates, could you let me know whether or not this series is present?
FGEX 52600-52999 appeared by October 1940 but was not present in the April 1940 edition. If you have access to the July 1940 Edition, can you tell me if this series is or is not present?
I think this is a narrow enough question to request offline responses if you can help.
