That is on the rear of the ram Steve. The idea being that you simply rotate the ram 180* to go from mill to slotter. Below is a photo of the ram from my Kondia (same set up as a BP) The head attaches to the Left-hand side via a knuckle that allows 360* pan and tilt. The slotter attaches to the Right-hand end.
That combination of mill/slotter effectively made the shaper extinct.
