Allgemeines Sturmabzeichen Zinc Rudolf Karneth?

[Tshnabs]

To me it looks like an unmarked RK, Hardware and pic look like an RK along with the back of the badge in my opinion. But would like the opinions of others, sorry these are the only 2 photos at the moment I'll try to get photos of the side for a better view of the hinge. Thank you for your help

Looks like a Karneth to me, the ball hinge is typical for this maker and I don't know any other makers who produced this reverse hardware although my knowledge of these awards and their variants is limited.
It compares well to other Karneth badges.

IMO, original with a replaced pin.
You can compare to my example.
