I hope we can get beyond the unintended controversey I seem to have begun and get on eith this most worthwhile idea. Jeff's Outfitters http://www.jeffsoutfitters.com/Default.aspx?categoryid=1 is the former Cape Outfitters and has some useful and reasonably priced items. Ballistic Products http://www.ballisticproducts.com/ has much information, references and loading supplies for shotguns. Kebco http://www.kebcollc.com/ frequnetly has some nice European items. AuctionArms.com is useful for guns, parts and other items. Some other easily found sources are mentioned in the posts above. I would be most interested in more European source. Particularly a British firm I ran across several months ago but delayed placing an order because they were scheduled to come to a large show near my home. The weekend of the show I was unable to go due to an emergency. As stated, I recently lost my old computer where most of my information was stored - another lesson learned the hard way!

BTW - that British firm makes various double gun parts for the trade. Both rough castings and finished parts. Sure wish I could remember the name!
