Optional T-slotted cross slide with a rear toolpost for parting off.

Optional boring table - to which the top slide could not be fitted. The Boxford version of this unit was rather more useful being just as long front to back but much wider.

Standard plain cross slide. Both the cross slide and top slide feed-screw housings screwed into their respective castings - unlike the Boxford type that, in later versions, bolted on. The only significant difference between the Hercus and South Bend compound slides was the engraving of the swivel degree markings into the top face of the cross slide instead of around the edge of the top slide base. 

Power feed apron - identical, apart from the 4 instead of 6-star clutch-engagement handwheel to the South Bend unit. An article on rebuilding a Hercus apron (amongst other interesting items) can be found here.

Not all South Bend clones used the same fixing for the compound slide feed-screw carriers, but the screw-in ones on the Hercus (both cross and top slide) were unchanged from the original.

Roller-bearing headstock: the large bearing-retaining plate and swollen headstock casting are evident in this picture of the tumble-reverse and changewheel assemblies.
