| FA/HDY.{William Hardy} ) FROM R.{Sir Henry Royce} F.{Mr Friese} HS.{Lord Ernest Hives - Chair} ) At Le CanadelHenry Royce's French residence. C. to SG.{Arthur F. Sidgreaves - MD} WOM. BY.{R.W. Bailey - Chief Engineer} CAR CHANGE SPEED GEAR. [STAMP] ORIGINAL RS{Sir Henry Royce's Secretary}/W13.1.30. [Handwritten] v 523. x 7310. x 5310- x 4510. I have asked Mr. Hardy to see if he can come here for one week clear, because I have for some time had a feeling that this year will see some good move on better change gears. I do not think it is done yet, and we would like to be in it. I have a 4 speed gear that should prove easy to make silent, and with the help of the Salerni coupling in its simplest form it ought to be easy to change. R.{Sir Henry Royce} | ||
