For Gerard and his colection of unexpected roundels : (I was recently on a RNZAF site) :

Kiwi looking rearward :

nice. The rearward looking kiwi is already on my website.

You could be right Gerard. Difficult to say because it’s a B/W picture. According to some sources (http://www.saairforce.co.za/forum/viewtopic.php?f=2&t=5485), from December 1920 (first roundel on SAAF aircraft) to December 1921 the roundel was (from center) Orange, Green, Red and Blue. From 1921 to 1927, the roundel was (from center) Green, Orange, Lemon, Yellow and Blue…

hmmm… I guess you’re right. It is the 1921 version

Learning every day!

South Africa (1921-1927) :

COOOOLLLL!! but according to Wikipedia this was used 1915 to 1921, after that the RAF roundel was used.

After the capitulation of the Netherlands in 1940 some planes fled to the UK. In the UK most of those were put in service with the RAF, like this Fokker T.VIIIw. The overpainted Dutch triangular roundels are still visible. It now has a small orange triangle under the wings and on the nose.

But how about this Argentina FMA Farman?
