| S/W. By.{R.W. Bailey - Chief Engineer} Copy to:- Hs.{Lord Ernest Hives - Chair} EP.{G. Eric Platford - Chief Quality Engineer} X8410 CWB3/GM/31.7.28. REAR SPRINGS 40/50 H.P. In the recent particulars of chassis delivered from W. I notice that there is a very great discrepancy between the poundage of the offside rear springs and the nearside rear springs. This is not the case with the 20 h.p. chassis where the rear springs are normally of almost exactly equal poundage. In view of the fact that the spare wheel is now carried in the rear and that for some time we have been endeavouring to limit the number of spare wheels to one, which would be carried on the nearside, this large difference between the poundage of the rear springs does not seem to be necessary and I shall be glad to know whether it meets with your approval. As examples, I note - 101-AL. 127 lbs difference. 98-AL. 84 " " 93-AL. 82 " " 91-AL. 96 " " 86-AL. 84 " " 84-AL. 84 " " 82-AL. 80 " " etc. etc. I had understood that a difference of 50 lbs was allowed for various reasons, but there are very few chassis now delivered which have not a considerably greater difference than this, whereas it appears to me, in view of the various changes which have been recently made, that this old difference of 50 lbs might well be reduced.
