Someone on AT who apparently shot for Wilson Bows said they were a Cam and a Half style hybrid, and if you look at the green module/cam track, they don't really look the same (top and bottom), but I don't know how you could rig a hybrid to the cam and make it work. They do look like interesting bows.

I don't think they are associated with Black Widow recurves though. I thought Black Widow was in Missouri. I believe the Wilson bows were made in Alabama, but not 100% sure.
