Bailey - Chief Engineer} +5810 R7/M23.2.29. SS.{S. Smith} WHEELS. X.7810 X.5810 X.3725 18-EX. I definitely prefer the smaller wheels as there is a definite advantage in lower appearance and lower gear. YOU will remember the struggle I had with the 20 HP. Dunlops said the smaller wheels would so reduce the life. Our 20 HP. wheels were much too large when compared with the 40/50. R.{Sir Henry Royce} | ||
