Pages 1 and 2 deal with the belt drive lathes whilst pages 34 and 5 concern the early geared-headstock models.

With a design dating back to the 1880s, the carriage of this swift lathe has only a vestigial apron supporting exposed hand-traverse gears and a box - with an adjustable lid to set the mesh - carrying the leadscrews clasp nuts. The compound slide rest feed screws are bereft of micrometer dials and the saddle carries six rows of T slots to better adapted it as a platform on which to bolt and then bore workpieces. The toolpost is typical of early English lathe-makers' practice with two loose plates supported on light springs.
Another example of early lathe design is also evident with the spindle thrust taken against an external plate supported on two bars tapped into the outside of the headstock casting; whilst effective in practice this method severely restricted the size of spindle bore that was, as a result, often left solid with an extra charge being imposed for providing a hollow shaft.
On this lathe the tumble-reverse mechanism (by which means the direction of rotation of the leadscrew could be quickly reversed, or remain in neutral) was mounted on the outside of the headstock casting whereas, by the early years of the 20th century, this tended, on larger lathes at least,  to be increasingly placed on the inside under the left-hand spindle pulley..
