I believe the Husqvarna museum is open to the public and they have a special display setup now to honor the 100th anniversary of the Model 310 shotgun. I wish I could see it in person.
There is a large firearms auction sponsored by Widforss in mid-May. They are just starting to list the items that will be up for sale. Here is a link to their website.
http://www.widforss.se/There are also lots of gun dealers with websites in Sweden. Try googling "Husqvarna vapen". If that doesn't work for you send me a PM, I have a bunch saved in my favorites list.
I must warn you that getting any firearms purchases home will be an issue. With the help of some friends of mine, I have a network of export dealers in Sweden and an import dealer in the US that knows how to work the license issues and even then it takes on the order of a year to have gun in hand in the US.
