I ran across an great little article on the 340 when I was looking for info on my Savage/Springfield 840E. If you haven't already found it, this might get you there. New to posting here and not sure how happy this forum is with off off site posts but here's a try: http://ataleoftwothirties.com/?p=978

If that doesn't work just google "The Savage Model 340: An American Classic".
