Interesting.
To my surprise, Logan did offer a couple replacement double tool cross-slides. I went back and look at the back pages of my Logan/Wards catalog and found this:

Neither is what Jerry has, obviously.
Logan used adjustable wedges rather than a rocker design to adjust tool height. It's interesting to me that neither can mount the standard compound in the front (as Jerry's can, as well as the one I built).
I haven't spent much time with lantern/rocker style tool posts, and no time at all with wedges. I wonder which is more fiddly to use in practice?
