X7310. -------------------- C. to WOR.{Arthur Wormald - General Works Manager} DA.{Bernard Day - Chassis Design} E.{Mr Elliott - Chief Engineer} P. 2. - L.H. & R.H. EASY AND SILENT CHANGE. -------------------- You are quite right; we intended to go on with the synchro mesh for P. 2. I am not at all definite whether we settled that Derby should do the R.H., and DA{Bernard Day - Chassis Design}/HDY.{William Hardy} do the L.H., but I know that I thought we must do the L.H., as it would need some careful work which might not get enough attention at Derby. The epicyclic unit we were examining was intended to be for P. 2., and to give silent gears and synchro mesh on all forward speeds. It will however take too long to get right so we must make P. 2. both right and left hand the same as the 25HP., and the more novel work we are engaged upon will stand until this is done. Derby can have a trial at the R.H. while we are doing the L.H., with exchange of drawings from time to time. We shall get both right fairly quickly now we have a good model in the 25HP.
