| BY.{R.W. Bailey - Chief Engineer} from DA.{Bernard Day - Chassis Design} c. to BJ. Hs.{Lord Ernest Hives - Chair} X. 7380 DA{Bernard Day - Chassis Design}2/M15.6.28. "SS{S. Smith}" BATTERY CROSS MEMBER. Herewith we send N.schs. 2631 giving the additional information as to the battery cross member which was promised on N.sch.2541 The inside radius of the small bend is equal to the diameter of the tube, and we have assumed that you will be able to do this. The first 'SS{S. Smith}' car will have a subframe. If body brackets are used when it goes into production we shall have to consider whether they alter the problem of this battery cross member.
