Prewar photos of Australian medium guns with tractors?

[Leonid]

Hello!
Does anyone have any prewar photos of Australian 6-inch howitzers, 60-pdr guns and 3-inch AA guns towed by artillery tractors or trucks? Despite all my efforts I was able to find only some photos with archaic Thornycroft "Hathi" tractor... As far as I know the wheeled gun tractors like Scammel or even AEC 850/FWD(R6T) did not reach Australia in the 1930s. Or am I mistaken?
Same request for New Zealand, however, in this case I've found at least some info in the "Royal New Zealand Artillery" site. Quote:"The Holts ceased to be used shortly after the outbreak of World War 2 when towage of medium guns was undertaken by Leyland trucks previously used to tow QF 3-in 20-cwt AA guns, the latter having been relegated to a static role..." There is also a photo of 6-in howitzer with Leyland 6x4 truck as tractor...
