That guy became a prominent Nazi https://en.wikipedia.org/wiki/Eric_von_Rosen
Two decades after Finnish air force had adopted it. Saying it’s Nazi imaginery based on that would seem a bit strange, like the property of something being Nazi travels back in time.
He was the Brother in law to Herman Goering lmaoooo. That “Swedish count” was a high ranking Nazi.
I don’t know if you noticed the 1918 there. I’m not sure even proto-Nazis were around that time.
