That's an interesting setup. A lot of the hand shapers that were made are traveling head shapers, but it looks like that ones shaper portion is removable. I wonder if that had different things that could attach to the vise, like a drill press or something. Also, I think I'd put a kink in that bar and operate it over the top of the ram so I can stand in front of the shaper and run it (that's how every other hand shaper I have seen is set up). Also, Gary Martin at Martin Model and Pattern sells a casting kit for a shaper about that size, if you really want one. Of course, you have to build it before you can use it.
