Wilbur gifted his younger sister, Adrienne, a copy of the American first edition, and dated it February 3, 1964. This is the earliest dated signed copy of WHEN THE LION FEEDS that I have ever seen, and had Wilbur had access on February 3, 1964 to a Heinemann British copy, he most assuredly would have instead given Adrienne a copy. Because he gifted an American copy, and because I have yet to see a signed Heinemann copy that Wilbur dated earlier than February 3, 1964, I declare The Viking Press first edition to be the true first edition, published before any other edition.
