Ed,

This is the kind of thing which makes trying to "date" ammo boxes a frustrating and almost impossible task.

I'd guess that these are just two separate printing runs and from the same general period. Depending upon which came first (and we'll probably never know), the typesetter's logic probably ran something along these lines: 1)"Oops, I forgot the S&W" or 2) "This layout certainly looks neat and clean and calls attention to the .357 caliber which is the most important part of this identification". (I'd bet that the one without the S&W, whether first or last, was followed by a phone call from the Factory attorney.)

Thanks for posting.

Bob
