I recently acquired this photograph dated July 8, 1929 of a Mk VIII "Liberty" tank demonstrating its abilities. A unit crest is visible on the sponson.
Lemons shows a similar scene on page 70 of Organization and Markings of United States Armored Units 1918-1941 but captions it as demonstrating for West Point Cadets in 1934 and identifies the crest as that of the Company F, 67th Infantry (Heavy Tanks). Can anyone confirm this?
