This manual is for the English Model D assembled and distributed by Gravely Overseas Ltd., Buckfastleigh, Devon, England. For potential American readers it contains footnotes explaining that "petrol" is "gasoline" and "parrafin" is "kerosene". Other footnotes show the American equivalents of the recommended British lubricants. It is undated, but must be 1953 or later because the parent company is shown as Gravely Tractors, Inc. The name change from Gravely Motor Plow and Cultivator Company to Gravely Tractors, Inc. was announced to dealers in January 1953.

Another undated edition of the English Model D manual, but in a slightly larger page format. Someone has anotated this one by hand with colored pencils to show parts interchangeability with the American Model D. A red dash next to a part name means it is not interchangeable. A green dash means it is interchangeable. A yellow bracket spanning a group of parts means they are interchangeable as an assembly. On most pages these notations are too faint to see on the digital copy. I'm investigating ways to remedy that.
