Here is something that may have all 4 and then some of the categories.
Looks like Schaller made this for Gibson. What’s unique about this bridge is the rail connecting the roller cam to the bridge forcing the bridge to rock with the string movement. It’s a great way to reduce friction of the strings sliding over the bridge. Not unlike a Fender Jazzmaster where the bridge is designed to rock with the movement of the strings. It’s been a while since I actually used one, I don’t remember how well it worked.
Any one have this on their guitar? I would love some photos to post along with it.
