List of 20hp tools - the small car with the big toolkit!
The Rolls-Royce 20HP.
The small (HP) car, with the big tool kit!!
by Peter Charlton
The 20HP was on the companies drawing board as early as 1918, but not seriously considered by the board until 1920. Two years later in 1922 the 20Hp was put into production. After the Great War, more people started to drive themselves, but most families that bought the new 20HP in 1922, still employed a chauffeur. The chauffeur not only drove the car, but maintained the car. To do this, the car came will a well-equipped tool tray. The 20HP turned out to be a great finial success for the company, the car was lighter, easier to drive and far more economical than the companies 40/50.
The pictures and spread sheet, show all the tools used in the 20HP tool tray over the cars production life.
There are two further tools to go into the picture. I did not realise until I took the photos and put the tools back. I had two tray items laying on my bench, that I forgot to put into the picture. I will leave readers guess what the two missing items are?
