The following points are the suggestions put forward by those responsible for testing the various sections in which they are interested, on new models before they are put into production. Transmission. Gry.{Shadwell Grylls} Gearbox. Road - 50,000 miles, including 15,000 in France.

" " } * This is a separate additional test run on new gears, but all other parts unchanged. It is most easily done by using a larger engine. The axle and gear boxes should be tested up and down mountain roads. IMW.{Ivan M. Waller - Head of Chateauroux} | ||
