Lathes badged "Harrison 11-inch" are just machines produced during the last years of L5A/L6 production; they have a 5.5" centre height but, instead of a screwed thread on the spindle nose, were supplied as standard with the safer and more rigid American L00 (L zero zero) fitting.

Harrison L5/L5A/11-inch with 3-speed screwcutting and feeds gearbox

The changewheels were made from steel, not cast iron, and as a result could set up quite a ringing noise at higher spindle speeds; careful adjustment of backlash between mating teeth, and the use of a heavier, "open-gear" lubricant helped to minimise this problem.

L5A/11-inch carriage with the thicker top slide casting that allowed the use of a T-slot to retain the toolopost.  This machine has the large bore, threaded headstock spindle.
