Indeed S&W marketed optics...I have several of their binoculars and spotting scopes. They also sold rifle scopes. Most were made by Hakko in Japan. Some are outstanding! (my 12x42 binoculars are quite the equal to any of my Leupolds)

A friend of mine here in Billings has quite a few of them he bought from a distributor a few years ago and some of them ARE the 7x50 the OP makes mention of.
