What is this overseas cap?

Thanks, guys. I'll tell my friend that the cap is Russian. Why it has a Luftwaffe cockade is undetermined.

If it has been used by a russian or other HIWI, then everything is possible. Those soldiers used everything.
Plenty of russian and german militaria out there used by the other side. So if this is an original cap, then it is a very interesting piece. To bad you dont know the story behind it- i would love to hear it.
