Oops, I guess I didn't look at the photo. Yes, definitely a different animal. I suspect the wedge one came first. I always heard it called the "Wegman" plate, so I assume someone called Wegman invented it. That system doesn't have much control. You can drive the wedge and get more torque, but that isn't reversible, or at least not easily. The one I tune is definitely too tight for fine tuning, a real struggle. So probably the Wurlitzer R & D guys (and they had quite a department at times) came up with this solution, which seems like a great one. If you wanted, before restringing you could remove them all, refinish the plate, clean everything up, lube if it seemed appropriate, and then reinstall, checking each for torque and adjusting. You could do an initial install using an electric screwdriver with a torque adjustment. Or you could just leave them in place as described earlier.
