Morris-Commercial Leader four-wheeled lorries for two-ton military load

Type C.S.10/80
This was a standard 10ft 6ins-wheelbase Morris Commercial Cars Ltd (MCC) commercial transport vehicle and had been tested for the carriage of two-ton military loads. The chassis was modified as regards tyre equipment and by fitting a double-skinned cab roof for protection from the sun in tropical countries, a number of them being operated in Egypt. The six-cylinder 3.485 litre petrol engine developed 63.5 bhp and drove through a four-speed gearbox to a worm rear axle. The wooden standard construction body was suitable for two-ton military loads. Trials commenced at Farnborough in April 1936 with a WD vehicle and performance was deemed satisfactory, with exceptionally good cooling. One of the lorries was fitted with standard tread tyres and tested in North Wales with similar performance to the Farnborough testing. Trials were to be carried out with a three-ton military load. A contract for 61 vehicles had been placed for the Quarter-Master-General and 11 for the Department of the Master-General of the Ordnance.

This is also from the 1936 Report. Shows you that the experience gained in Egypt led to improved air filtration, and this obviously was of considerable benefit in due course.
