I haven't seen a lot of vintage RR owners on this site. Here's what I've found out after a quick Google search (Please come back and let us know how you make out):
"The engine is a conventional six cylinder, single block with a detachable, cast-iron head. Overhead valves are operated by push-rods. A bore of 3 inches and a 4½ inch stroke give a capacity of 3,127 cc. Oil pressure is by gear pump. Ignition is by Rolls-Royce coil with a stand-by magneto as an option from 1923 and as standard from 1924. The main distinguishing feature of the 20hp is its horizontal radiator shutters which were changed to vertical in 1928 at chassis number GFN71. The transmission was initially by centre-change three speed gearbox with a central handbrake. The handbrake was moved to the right hand side in 1924 and a four speed right hand change box was fitted from 1925. The clutch is single dry-plate driving an open propeller shaft to a spiral bevel back axle. Fuel capacity 14 gallons with gauge on the tank. Fuel delivery by Autovac. Earlier cars in chassis form weighed 2,305 lbs. rising to 2,635 later. 2,940 were built."
