Yes, not only have I heard of the 96, I have some info in the copy of the 1909 catalog I have.
This is what it says in the catalog:

41/64-inch bits. Drills holes up to 1 1/4 inches.
No. 96 Champion Quick Screw Return Self-Feed Drill. Wt.
135 lbs. .................................................. .$ 12.50

--------------------------------------------
I would say it's a much larger, and better vise than mine, which weighs 80 lbs. I wanted mine for the small size though...You can swap the handle onto the other gear to change the speeds, it's a manual process to change speeds by moving the handle.
Could be similar to this one I will attach, which belongs to Ron Reil, but I don't know the model of Ron's post drill (this one, he has about 3 or 4 of them I think).
