Trev,

Now that ralf MArtini and Martin Hagn have each gone their own ways, I wonder if you may be able to get the same rifle made by Hagn if you asked him? In any case, AFAIK, the manufacture of the actions had been contracted to Hartman and Weiss for a time - not sure if it still is. But they may also be able to build a double rifle for you if they still build the actions, I guess.

Good hunting!
