Bonde,

Recknagel makes what you want, and the Norwegian importer is Ragnar Hansen in Vestfossen.

However, I don't know if he has much (any?) experiance with double rifles, even though he has a lot of big bore experiance. He is also known to be a bit hard to deal with...

Another person you could contact here is Per Arne Vågsland in Drangedal. I've been told that he can regulate double rifles, and I have the impression that he might do more double rilfe work that Hansen.
