Hello gasgunner - new guy here - very much enjoy reading all the posts. I have an original german stalking rifle that my dad brought back from ww2. The action looks identical to yours and is also not marked. The barrel is 8.15 by 46R and is marked T. H. Kommer. Like WJW, I have also heard it referred to as a Schmidt & Habermann. My action has no link from the lever to the breechblock, but uses an unusual (to me) camming action. Is yours similar to this? My rifle was made in Zella Mellis (sp?)
and was proofed in May 1939.
Regards, Joe
