R3/M1.5.24. -2- Contd. (1) Direct foot to rear axle only - present 40/50 leverage. (2) Direct foot to 4 wheels - half present 40/50 leverage. } This gives equal clearances. to see which scheme gives the better direct braking. I am hoping to see these temporarily fitted during the first few days in May, at WW. R.{Sir Henry Royce} | ||
