 Morris invested another £300,000 in extending the Gosford Street factory and in buying new machines.Having re-organised engine production from batch to flow, Woollard introduced a 24-hour working day, by introducing a 3 shift system of 8 hours each, for a 5-day week.Production increased from less than 300 power units per week in January 1923, to 600 units per week in December of that year and to a remarkable 1200 units per week in December 1924.
