I don't like it badger.
The swastika looks very poorly formed.
Is that an L18 stamp (Mayer) on the pin? If so it is a zinc variant I have never seen before
If it is L15 the good chances are it's a Floch fake especially with that oval hinge plate.
I think the jury is out as to whether these crosses were done pre or post wars end but I see too many minters to have one in my collection.
