Barker swivelling headstock with backgear selection lever
Screwcutting was by changewheels with a set of 17 being supplied to generate all common English pitches from 2 to 60 t.p.i.
Both sliding and surfacing feeds were selected and engaged by a single 3-position lever on the front face of the apron. A small plate riveted to the lathe instructed the operator how to use the automatic release for the sliding feed: "Use reverse box lever as a dead stop . Traverse lever will then disengage easily".

The tailstock end bed-socket casting carried the machine's serial number - in this case possibly decoded as February 1947 and (with numbers likely to have begun at 101) the 311th machine built.
The No. 2 (later No. 3) Morse set-over taper tailstock was designed with a usefully exaggerated "lean forward" for the barrel that allowed drills and other fitting to reach right up to the spindle nose.
A pair of bevel gears under the headstock transmitted a drive out to a conventional arrangement of changewheels carried on a slotted bracket.
