I found this pin with a group of military pins and ribbons. The bird on it looks like the messerschmitt logo but I have not been able to find any Messerschmitt logos with the red 0 like this pin.

I cannot verify its authenticity.   However, "【不撓不屈】Fu-Tou-Fu-Kutsu (never giving up)" is his most famous motto.

Is this a Turkish Officer's hat badge?     

Hey there Sarge, the air vents appear to be zinc, they are not magnetic.    Thanks!
