I've found this for sale as "airgun", seller has no idea what it is. I don't recognise it but it looks like one of the German military trainers.
It does not have the triagonal fulcrum for the cocking lever like the Haenel or the Anschütz, nor does it have a magazine but what looks like a loading port in front end of the handguard.
It seems it is a straight pull cocking mechanism
Does anybody recognise it and what might it be worth roughly?
