As we have now learned that single ended butted tube can be obtained at very small extra cost we send herewith N.Sch.4974 showing the butted tube applied to the design of side and cross steering tube shown on N.Sch.4964 as an alternative to the thick tube turned down for the majority of its length. E/Lid{A. J. Lidsey} is obtaining comparative costs of all the designs which we have sent to you as soon as it is possible, and then we hope to be able to tell you which design to detail for both Phantom III, Wraith II and Bentley III side and cross steering tubes.
