| X 3746 Extract from Hs{Lord Ernest Hives - Chair}3/lg 9.12.19. X.3746. X.3647. As regards the improved type of piston fitted with a ram with three ring, the drawing for these are promised for tomorrow. We anticipate it will be 10 to 14 days before we can get a set of these improved pistons running. X.3718. We are anxious to fit some ram pistns to the car which is to run 10,000 miles. To keep this appointment in France, this car must be completed in 10 days, we cannot therefore, fit the improved pistons. Now that the amount of over-oiling with the present ram pistons is not too bad, we have hopes of being able to improve them sufficiently for them to be used. Hs.{Lord Ernest Hives - Chair} | ||
