For the attention of Mr. Robotham. Messrs. Rolls-Royce Ltd., Derby. Dear Sirs, With reference to the two faulty Telegage heads recently returned to us, which we understand were taken from your Continental car, these have been replaced and returned to you. Leaks were found at the top of the tube in one instance, and at the bottom of the tube in the other. Both these heads were of the old type with the short capillary, and from an examination of the clearances in the body castings top and bottom, we are of the opinion that the tube and its holders were under some strain in both instances which caused the leak. In the later type which we have been delivering to your production orders, the body castings have been altered, | ||
