This unusual and compact drive system is fitted to an early Colchester Triumph. A motor, carrying a fabric universal joint on its shaft (as commonly employed on pre-WW2 cars) drives a standard worm-reduction right-angle gearbox. The gearbox output shaft - carrying a 3-step cone pulley - is supported in brackets with the one closest to the lathe being inside the headstock-end leg. As the leg is cast with a hole for the shaft to pass though this assembly is very likely to have been an original Colchester system.
