| contd :- we still are preparing 21-EX car which we hope will be the final model car. 22-MX {John H Maddocks - Chief Proving Officer} car was rushed away in order to establish the design of the frame. After the design has been established it will still take some time to confirm that the best is being obtained from the design. We expect to have 21-EX car ready in about 10 to 14 days. This car will then be sent round with a standardisation sheet so that all the officials on the sheet will be able to try this car before signing the sheet. -2- ins. | ||
