Messrs.Rolls-Royce Limited, DERBY. Dear Sirs, We are sending you two tubes of each of the Radiators which we are constructing for your bumper test. We have made enquiries regarding the process of production of these tubes and find that each is drawn from its own separate blank and they are not cut from lengths. We expect to deliver the Radiator with the smallest diameter tubes tomorrow and a further one on Saturday. It is particularly desirable that the attention of Mr.Bailey and Mr.Hives is drawn to the method of making the joint of the inner side panel to the bottom and top headers. To the mind of the writer, this was a weak point of the design which would lead to ultimate leakage at the extreme corners of matrix and you will see that a reinforcing strap of 20s gauge metal is used for the purpose of making a lap joint with the two headers and this side panel which is made more important by reason of it conveying water. This point can be examined by taking away the outer nickel panel by means of the two securing set screws and springing it a little at the bottom. The tubes which we have procured have all proved to be of very excellent quality both in work and on the final test, as we scrapped all doubtful tubes at the tubetest. The quality of the Cupro Nickel Silver has been some-what disappointing, as the surface was not so clean as we could have desired, but this is a matter which we are taking up with Messrs.Wiggins, with a view to improvement.
