Wor.{Arthur Wormald - General Works Manager} Ry. X.523 X.7310 X.5310. X.4510 CAR CHANGE SPEED GEAR 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 Selerni coupling in its simplest form it ought to be easy to change. R.{Sir Henry Royce} | ||
