I've been building my armo 1/35 austin-kegresse for quite some time now and its ready to be painted. The problem is that I can't quite figure what the base color was.
Books such as osprey state that it was grey, but the color photos from 1939 show a light fieldgrau type color. I took black and white photos of different colors and tried to match them to the photo, and it seems that a light green is a closer fit then grey.
I've attached a photo of the armored car that I am building and the color picture of a kegresse from 1939, and maybe someone on the forum knows what the original color was without any guess work.
Your first photo: It had been taken in Polish-Soviet war 19-20 Polish Army captured then 2 soviet armored cars - half-track Austin -Kegresse ( first - 21.03.1920, second - 26.04.1920). Typical for this armored cars are incriptions with red letters in grey background. Next photos presents a monument of armored car in polish colour (photo taken in October 1939). More informations about it you can find in book: "Armored Units of the Russian Civil War", Osprey. Mr philthydirtyanimal in Your photo we can see camouflage of half-track Austin -Kegresse in Red Army at time 1922. Yours.
