Despite a vast range of grinding machines and associated equipment, Churchill were not well-known as a maker of conventional industrial (engine) lathes. A modest range of especially well-made and tough models was offered during the 1920s and 1930s - the earlt C-R and N-M types - these having (as with so many other makes) the option of a "cone" pulley headstock for flat-belt drive from factory overhead line shafting, or an all-geared alternative. Even the latter (termed a 'selective drive' by Churchill) could still be had without a built-on motor and instead supplied with what was often called "single-pulley" drive i.e. a flat-belt pulley to take the drive from line shafting.
