| contd :- -2- As regards the size of the wheels fitted to 18-EX. There are no reasons why these wheels cannot be used on SS.{S. Smith} cars, at least they can be used on light cars. They improve the appearance of the car. We shall however be testing both 21" and 20" rims on 'SS{S. Smith}' cars. Hs.{Lord Ernest Hives - Chair} | ||
