Besides the usual range of accessories including chucks, metric conversion gears, fixed and travelling steadies, toolposts, large faceplates, toolpost grinders, boring tables, and collets, etc., the Viceroy was also available with the rather unusual taper turning and copy unit illustrated below.
The taper turning part worked in the normal manner and for copying, a master of the item to be reproduced was substituted for the swivelling taper plate. Copying was limited to a "climb" angle of 32 degrees inclusive. This is the same as moving from zero diameter to 613/16" diameter per foot.
