There are a couple of great Swiss forum resources - one of them right here on CalGuns:

Also, here is the link to the official "Swiss Rifles forum"

And here is another good one:

And one more - this is a reference table for corelating serial numbers to year of manufacture:

Should get you going and give you plenty to absorb for starters!
Great guns - and $330 is a very good price IMHO.
Enjoy!
