Rolls Royce Ltd., DERBY. For the attention of Mr. W. A.{Mr Adams} Robotham. - 1023 - Dear Sirs, Your letter of the 15th., addressed to Mr. Breeden, has been handed to the writer for attention. We can, if you wish, proceed immediately with a sample bumper, but wish to make the following points bearing in mind that you may wish such a bumper to become a production job. 1. It is preferable at the upper and lower portion of the bar to incorporate a larger radius than shown on the drawing, otherwise trouble results in polishing and there is a tendency to uncover the nickel. It is appreciated that the larger radius tends to destroy the sharp line, but from a production standpoint there is no argument as to which is the best thing to do. The merging of the section at the ends of the bar, whilst ideal from an appearance standpoint, introduces a difficulty in production, and it might be necessary to slit the bar at its longitudinal centre line, shape the ends and then weld, which is costly.
