The simplest form of tailstock available for a watchmaker's lathe. The "push barrel" is capable of holding small collets and the unit is intended for centring, turning work between centres and checking the concentricity of components.

Plain (no screw or lever feed) but heavier-duty tailstock which holds the same type of collet as the headstock. This design was available for the WW, Large Lathe, Magnus, Elect 750 and Model A.

The most complete, versatile (and expensive) of the tailstocks the "Combination" had a rack-and-pinion drive to the barrel - and accepted the same collets as the headstock. A version of this tailstock was available for all Models of Derbyshire lathe

Lever-action Revolving Tailstock - intended for deep-hole, high-precision, small-diameter drilling this was, in effect a modified headstock which allowed a drill, held in a collet, to be rotated at very high speed.  A micrometer barrel was attached to the side of the unit to allow precise depthing.
With tiny drills the problem is to attain the correct cutting speed; by rotating the headstock (holding the workpiece) in one direction and the drill in the other - at up to 10,000 rpm - an efficient cutting speed is more easily obtained.

The Half-open tailstock is a traditional design originally intended for light duty, mass-production work. The idea is to have a selection of barrels to hand, each equipped with a different tool, so that a series of operations can be carried out in rapid succession - in effect, a poor-man's capstan unit.

Closed tailstock with lever feed - designed for the same type of work as the open tailstock - but slower and more cumbersome to use, if rather safer and stronger when handling heavier jobs.
