These specifications remained until the following revisions were
recommended by the AAR's Car Construction Committee in 1959: Section
1, Paragraph (c): 9 inch letters for reporting marks and 7 inch
figures for car number shall be used on the sides of the car and 4
inch letters and figures used on ends of cars.
Was a different size previously specified for the end lettering, or was that previously unspecified?
