Possible Suhl proof mark on Kettner stalking rifle

[David Lapell]

I acquired recently a Eduard Kettner rifle recently and I have been looking at the proof marks, and there's one I cannot decipher. I have been told it's possibly a Suhl proof mark because of the hen, but it is not in The Standard Directory of Proof Marks and I cannot find it online. Is it from Suhl and who did it actually belong to?
