Next to smallest of the conventional George Adams conventional precision lathes was the 2.75" centre height by 12" between centres, backgeared cutting Model CS. The bore of the cast-steel "glass-hard" spindle was 10 mm (0.4") and took GA collets of size B with a maximum bore of 6 mm and a nose capacity of 8 mm; the spindle end was also threaded to accept conventional screw-on chucks and faceplates.  The spindle bearings were ground cast steel with a ball-bearing race to take thrust.
The bed was of an inverted V type, with two Vees, one to align the headstock and tailstock the other to guide the saddle. The feet were cast  integral with the bed - and had a rather early American Rivett look about them.
Arranged for round-belt drive the 3-step headstock pulley carried three circles of dividing holes with 60, 42, 36 and 24 indents. The lathe was obviously built to metric standards - it carried a 2 mm pitch leadscrew, a tailstock barrel micrometer dial graduated in 0.1 mm increments and metric graduations on the (typically tiny) compound slide rest dials.
The hand-operated rack feed to the carriage was direct - there being no intermediate gears - and hence the travel was "high-geared" and rather rapid.
Fitted with tumble reverse, the lathe was supplied with 23 changewheels that allowed a very wide range of English and metric threads to be cut. A travelling steady, hand rest , centres, spanners and headstock dividing pointer were all supplied but no motor or countershaft - these were available at extra cost in various forms for wall, bench or foot-treadle mounting..
