And Bf109s and MS406s.
I know the ME-109, of course. Will have to look up that MS-406.
Sweden (not talking Swiss now) impounded some P-51's that had to land there in WWII and interned the pilots. They then operated the planes and bought more after the war, I think. Their insignia is three gold crowns in a round blue field, if you see a photo of a Swedish Mustang.
