You are really only dealing with type A, type B, and type C roundels in AH.
Although you will run across occassions when a variation is used or a different size will be used.
Dates -
Up to mid 1942 - Type A
After mid 1942 - Type C
What the roundels on the linked page don't show -
The Type A roundels used a slightly brighter shade of red than the Type C.
RGB values I use for the red -
Type A - 188, 32, 7
Type C - 152, 32 , 6
Just about all will use Type B upper wing roundels, apart from aircraft assigned to 2 TAF after Jan 45, they used Type C.
good guide for fighters -
If camo is brown / green - more than likely Type A and B
If camo is grey / green - more than likely Type C and B (bearing in mind 2 TAF)
BUT - There are instances of brown / green camo aircraft with type C roundels.
Photographs are the best guide.
