Hello!
Anyone knows what trucks(tractors) were used to tow Australian 3-inch 20 cwt AA guns before 1939 when Ford Marmon-Herrington 4x4 was adopted as standard field artillery tractor? The problem is that I've found some photos of Australian 3-inch 20 cwt dated 1938 (but unfortunately without any "towers" in picture area) and one photo of these guns towed by Marmon-Herrington tractors (date of creation - circa 1940, State Library of Victoria)...
