| BY.{R.W. Bailey - Chief Engineer} from DA.{Bernard Day - Chassis Design} c. to BJ. Hs.{Lord Ernest Hives - Chair} X. 7230 DA{Bernard Day - Chassis Design}4/M25.1.29. 'SS{S. Smith}' EXHAUST SYSTEM. We send herewith N.sch.2807 shewing the plain parallel sliding joint on the front expansion box, and also on the silencer, as an alternative to those shewn on N.schs.2805/6. Though yesterday we suggested your going on with N.sch.2805 we think it is probable that R.{Sir Henry Royce} will wish to try the plain joint first, so that we suggest now that you should proceed with N.sch.2807 with the modification to N.sch.2806 shewn in the bottom r.h. corner, and not proceed with N.sch.2805 until you hear further.
