At the risk of breaking a site rule, even the British Fleet Air Arm was known to use the swastika. This is a Blackburn Dart landing on HMS Furious in 1926. The use of the swastika by Finnish Air Forces pre-dated the rise of the nazi's in Germany. However laws are laws and some national sensitivities are understandably greater than others.
