Who knows this unit marking?

[milvz]

hello forum,

my name is andre and i live in germany. this is my first posting in these interesting forum.

a friend of mine has two storage boxes for a German motorcycle. On it is to recognize a federation badge which is unknown to us.
Even a comprehensive research has so far brought no answer. Since the picture is a bomb (or possibly a V2 rocket), I suspect that this sign should come from the Luftwaffe.

Can someone possibly say something or even dissolve it?
Thanks in advance!

I've looked everywhere, I don't think it is a Luftwaffe unit.
