In the case of the Bentley and 25 HP., the timing is not so difficult, although we have had recent cases where the tower has been damaged in excessive removing of the cam for ignition setting purposes. Here again it would be an advantage to have a similar scheme to the one described, and it would be greatly appreciated. The practice of turning the distributor head to set the ignition is common to all American and English cars, and our present method is somewhat out of date. Hs{Lord Ernest Hives - Chair}/P.Dodd.
