After Googling a bit I found that Cuneo died in 1984, so obviously he had time to finish his WW I work. He seems best known for his history of Rogers' Rangers.

Cuneo, John R., Drawings, Acc. 1987-0025

John R. Cuneo (1907-1984), a lawyer, began Winged Mars with the intent to write a multi-volume history of the air forces of Germany, France, and Great Britain through the end of World War I. The first volume, The German Air Weapon, 1870-1914, was published in 1942 and traced the emergence of German aviation to the outbreak of the war. That volume was followed in 1947 by The Air Weapon, 1914-1916, tracing the functional value of airplanes as weapons during the first two and a half years of the war. Cuneo planned two additional volumes in the series to complete the history of these air forces to the end of 1918, but he abandoned these plans when his publisher, Military Service Publishing Company, canceled the contract.
Contents: Fifty-five unpublished pen and ink drawings done by Cuneo for The Air Weapon, 1914-1916. The drawings were deposited in the Institute of Aeronautical Sciences and in 1960 Cuneo retrieved them with the intention of having them published as a separate volume. At the time of his death the drawings had still not been published.
