VR-2 fitted with the Model A Profil-O-Matic Fluid-control Duplicating Attachment. The additional equipment did not interfere with the millers ordinary functions. In the Model A attachment both the stylus unit and the hydraulic cylinder controlling the vertical traverse were built into Profil-O-Matic head. This unit was available to fit the VR-2, VRG-2 and VRG-5 Models.

Model B Duplicating Attachment (as available for the VR-2, VR-3, VRG-2, VRG-3, VSR-2 and VSR-3 Models). On this version the stylus unit was fitted to one side of the main column and carried on three slides. For vertical control, a hydraulic cylinder was built coaxially around the knee elevating screw - the design allowing the use of the standard milling head.
