http://www.jagdwaffen-just.at/englisch/erste_seite01.htmIt is an standard grade Ferlach drilling with common "Blitz-" = triggerplate locks. Nothing really special or exceptional here, neither in design nor decoration. The only thing unusual here is the chambering of the rifle barrel. IMHO the use of the rimless, high-pressure .264 Win Mag in a drilling is an outright silly idea that will lead to problems sooner or later.In the 1960s the Ferlach gunmakers built anything a customer asked for.
