Chassis. to Referring to the attached Standardisation Sheet, B.J. would like to know whether you recommend this additional fitting on Chassis for Open Touring Cars as well as for Closed Cars. Supposing it was not fitted to Chassis for Touring Cars, could it be easily fitted afterwards if necessary? He also noticed that total miles run appears to be only 1500, and would like to be assured that you are satisfied with the device despite the comparative shortness of the test. Att: Sg.{Arthur F.
