X1698 Ref 21EX & Phantom I Ph ALL HsL/LcL.7.29. SS{S. Smith} X7380 X7770 R 'SS{S. Smith}' CARS. Since we sent 21-EX car to Sales we have been able to effect definite improvements to the SS.{S. Smith} cars at Derby by giving attention to the detail mounting of the subframe. By this means we have been able to reduce the resonance in the body to a considerably extent. We are still however not satisfied with the amount of noise and fuzz which can be heard in the driving seat - in this respect we think we are worse than the Phantom and are now giving our attention to this. By the end of this week we hope to have two SS.{S. Smith} cars which will represent the standard we might expect from production. We would like to carry out comparative tests with these cars against a standard Phantom Trials car - if they are then considered unsatisfactory, we propose bringing the Phantom and SS.{S. Smith} cars to WW. so that we can go over the various points with you. We should like Sg.{Arthur F. Sidgreaves - MD} to arrange a meeting place for the cars on Monday the 8th., and if necessary we could be at WW. on Tuesday the 9th. Hs.{Lord Ernest Hives - Chair} | ||
