1925 Rolls-Royce Twenty 20 hp tourer

Made 1925-1926
Automobile, full size, Rolls-Royce Twenty, four-seat open tourer body, 20 hp, number plate 4402, chassis built by Rolls-Royce Limited, Derby, England, in 1925, chassis No. GSK10, body built by Smith & Waddington, Sydney, in 1926, includes toolkit and handbook

The Rolls-Royce Twenty is easily recognisable from other Rolls-Royce models with its horizontally arranged radiator shutters. The Rolls-Royce chassis is pressed steel, with a parallel girder and tubular cross members. The suspension comprises semi-elliptic springs, front and rear. There are friction type shock absorbers and a single dry-plate type clutch. The car has four forward speeds and a right hand side gate change. The engine is a 6 cylinder in-line, mono-bloc with push-rod operated vales located in a detachable cylinder head. The radiator is of German silver.

The body design is a four seat open tourer. The entire body plus the mudguards are aluminium except for the door hinges. The front seat and all floor boards are removable, giving access to the chassis. The back squab is also removable, giving a much larger luggage carrying capacity.

The body of the car has been painted with a thin coat of grey paint which is not original covering the original maroon primer/undercoat. The windscreen frame has been painted black and would have been nickel plated originally.
