Another difference in two boxes of Winchester .357 Magnum ammo: The pic below is the end flap of two 1935 style boxes (before the Western and Olin callouts). One refers to the round as the S.&W. .357 Magnum while the other doesn't mention S&W on the flap. These two boxes share one identical side but the second side is different. Thought it was an interesting note.
