I've never came across one, with the offset, Not to say they don't make one. Though they do use a lot of pressed-in inserts that are offset.
Yep, Overloaded that looks close to the ones I programmed (though they look like the ole style). Hard to tell, they do make a lot of them, I programmed about 26 variations, (So far) parametric program, same basic shapes just a variation each. Small block, Big block Chevy/Ford/Racing of each style.
