These are good folks we know who might also have interesting items:
Classic Firearms & Parts, LLC
Scott has parts as well as guns and many other interesting items.
These folks sell reprints of catalogs, books and fliers. They have spent years finding interesting items. A great source for information.
Ray Giles is a great guy with a super website. If you don't have his book on Winchester Ammo Boxes you should get it right away, it is full of photos and well researched information.
We will be adding other names and sources soon. As soon as I figure out how to make those little blue links appear, this will look better.
