Thanks for the warm welcome, I'm sure here is a lot of information to share.
But I have to say that now I am living in Switzerland ( in Zurich , a very nice place as Homestader said :grin: ) but I am from Spain.
So at this moment probably I've more information about spanish guns. :redface:
The gun-laws here - in Switzerland- are not bad in comparison to other european countries but there are some limitations for a foreigner. Currently I'm cheking with the autorithies about the legal requirements for muzzleloader home-building .
Meanwhile I'm preparing my designs / tools ...
