| S/W. Hs.{Lord Ernest Hives - Chair} x5410. re- 20/25 h.p. Chassis - Special Touring Saloon. Cx{Major Len W. Cox - Advertising Manager}5/KW15.1.32. Sg{Arthur F. Sidgreaves - MD} has asked me to get in touch with you with a view to getting clearly defined the situation with regard to suspension arising out of the original proposal to fit special flat springs and possibly Hartford shock absorbers on any 20/25 h.p. chassis which was likely to be used for maximum speed work. Sg{Arthur F. Sidgreaves - MD} sent you two lengthy memos of mine which I think fully represented the situation from the start and we are anxious to be clear here in talking to customers as to definitely what is necessary in the way of departures from standard (if any) on 25 h.p. chassis intended for fast work, and in consequence fitted with the low rake of steering (F) and possibly a light body of low build and reduced wind resistance. Can we take it that it definitely is not necessary for you to fit special springs nor additional shock absorbers, and that either standard springs of the non-low rating type, or standard springs of the low rating type, would be suitable in any case in conjunction with the standard hydraulic shock absorbers. If that is definitely the case then obviously there is no need to depart from standard at all in such cases, nor is there any need to impose any supplementary charge on the customer for special fittings. We understand that as from the 101st chassis in "T" series the F steering column can be regarded as an alternative standard. Perhaps you will kindly let me know if we are correct in assuming that there are no special features about the 25 h.p. chassis for fast work in future, and we shall then know how to deal with the matter here.
