My Cousin inherited a bunch (like 10) different surplus guns from his father. he has swiss, belgian, french, german, and japaneese guns. Is ther a website or book that would give good info on value? Any help would be nice.
lots of books on the subject. I'd start with a general all-inclusive sort of guide to get an idea of what everything is and what prices to expect. From there I'd look on gunboards and gunbroker to figure out what they are going for now. Some things are always sought after, and some things are plentiful in the market already and won't get what they are valued at. It all depends.
The book I got from an online bookstore is:
"Standard Catalog of Military Firearms: The Collector Price and Reference Guide" by Phillip Peterson. I have the fourth edition, don't know if they've put out a newer one yet, but it's pretty good overall for general history and price ranges.
