Looking for basic information on camouflage colours applied to Auster AOP9 (c.1950s/60s). Having viewed a number of photographs on various websites it seems to me that these aircraft were painted in two colours that were not the old dark earth/dark green combination. The colour combination appears to be two tones of Green. Any help on this subject would be appreciated...a pointer towards the nearest Humbrol colours would be a good starter. I am after an approximation rather than any deep conversation on colour codes but please, be my guest here. As I said any help will be much appreciated. Thank you.
