World famous Rolls and Royce agreed to design, develop and bring forth a range of two-cylinder, three-cylinder, four-cylinder and six-cylinder automobiles, all evidently borrowed from Royce 3 test-bed twins. The visualization was to initially produce nineteen 10hp cars, whereas only seventeen ended up watching the grey road. All of the 10hp Rolls Royce’s, Type A, featured a two-cylinder powerhouse with only three-bearing crankshaft and two camshafts working the overhead intake valves and side exhaust valves. The 1.8-litre engine delivered power through a conical clutch to a 3-speed sliding transmission box with shaft drive.
All of the A-Type 10hp models had a prefix 20, production models starting with chassis no. 20150, we believe were known as a Royce contributing to the fact that, there is not any known reference to Rolls’ involvement with that automobile. 20151 can be considered as the 1st Rolls-Royce motor car as a result of the marketing agreement of Rolls and Royce. The engine for this car had its trial run on twenty first of August 1904 and the car given to sewing machine giant, Paris E Singer, a friend of Rolls. 20152 came into life on 27th September 1904 and probably was the first car to have the classic Rolls-Royce radiator design. This Barker-bodied model was given to Joseph Blamires of Huddersfield. 20153 was born on 10th October 1904, with coachwork commissioned from the famous Cann of Camden and was given to a Lt. Col. Moffatt, Wiltshire.
