I've got a 1990's Fadal VMC-3016 Standard Model. Has a 7,500 RPM spindle and the 88HS.

The book, on ppg 11 says there are two different Orientation Bridge assemblies. ORB-0001 or ORB-0002. At least 20 of the parts are the same in both assemblies.

Is the L shaped casting for the ATC the same for the servo version as the one for the standard Geneva drive? It looks the same in the assembly drawing.
