X7120 To Hs.{Lord Ernest Hives - Chair} from Sg.{Arthur F. Sidgreaves - MD} Copy to Wox. E.{Mr Elliott - Chief Engineer} BY.{R.W. Bailey - Chief Engineer} PN.{Mr Northey} Cx.{Major Len W. Cox - Advertising Manager} re P.II Production. X7770 Sg{Arthur F. Sidgreaves - MD}18/E14.9.32. Referring to Hs.{Lord Ernest Hives - Chair}1/AD9.9.32. and other memoranda on the same subject, we are agreeable to the standardisation for the Continental Model of the following features: Compression ratio 5.25. New Camshaft having higher lift and longer duration. Semi-expanding carburetter. These three were 10,000 miles tested on 19-EX. Approval to the carburetter is really subject to your being able to improve still further the starting from cold, which I gather you anticipate being able to do without great difficulty. Re the exhaust, we agree to the standardisation of the resonant type of silencer for the Continental model, but not for the ordinary car until you are able to show us an improvement of it from the point of view of silence. The above means that the standard car will remain unchanged as regards carburetter, governor, exhaust and camshaft. The compressed ratio has, I believe, been standardised at what the Continental has been prior to this further increase. On 58-GN you have also fitted stronger clutch springs, stronger tappet springs and valve springs, modifed exhaust valves. If these have been 10,000 miles tested and you want to introduce them, I see no objection to their being introduced as soon as material commitments permit. If you think any of them are sufficiently important to warrant scrapping of existing material, please let me know so that the question of the £.s.d. side of it can be investigated. The only other two points, which you have fitted up on 58-GN, which I think are not covered by the above, are the | ||
