A rarely-encountered drive configuration used two-speed Brook Compton motor and an electrically-actuated disc brake. The normal "plug-in" electrical control panel on the front of the stand was abandoned and four switches, together with a stop button, were arranged in a line beneath the chip tray and in line with the headstock. A third shaft, fitted below the leadscrew and powershaft, ran along the bed and was operated by a lever attached to the right-hand end of the apron - in an arrangement not unlike that employed on a Mk. 1 Bantam. At the right-hand end of the shaft was a box containing a cam which operated the necessary reversing switchgear  manufactured by Klockner Moeller.

An unusual main spindle configuration found on a Mark 1.5 Student fitted with the rare Klockner Moeller reversing switchgear. On some of the Klockner-equipped lathes an unusual (and presumably heavier-duty) main spindle arrangement has been found where, instead of the components being located by a single key a much heavier fully splined shaft was used with the sliding components engaged by dog clutches. If you have one of these models the writer would be interested to hear about it.
