I just purchased a Rock Island 571 vise yesterday. After unscrewing one of the jaws to clean it up with my wire wheel I noticed the design of the jaws on this vise look exactly like the jaws on my Craftsman 5195. So I unscrewed one of the jaws from the Craftsman and examined the screws that were used to secure it in place. They are identical. See below. The Craftsman screw appears on the right in the photo. Rock Island is the only vise manufacturer that I am aware of that used machine screws with that particular taper on the heads. Nobody else used them. They are unique to Rock Island as far as I know. I tried securing the screw from the Craftsman into the jaw of the Rock Island 571 and it was a perfect fit. And the screw from the Rock island fit perfectly in the Craftsman jaw.
In my opinion these Craftsman vises were manufactured for Sears by Rock Island.

I followed this observation up by examining the screws from other vise manufacturers as well. Here are the screws from 5 different vintage vises. From left to right they came from the following: Dropfo 3, Craftsman 5160 (which I believe was also manufactured for Sears by Rock Island), Craftsman 5195, Reed 2C, and Prentiss 19. The only two screws that match in terms of the taper are the Craftsman 5160 and the Craftsman 5195. And they both match the screw taken from the Rock Island 571.
I am convinced that these 519X Craftsman vises were manufactured for Sears by Rock Island.
