The Rolls-Royce 25/30, built between 1936 and 1938, is an updated version of the 20/25 featuring a larger engine than had been fitted to the earlier model which provided more power to compensate for the over-size bodies being built. The in-line six cylinder, overhead valve, engine was similar to that used in the 20/25 but increased in capacity to 4,257cc. A single proprietary Stromberg downdraught carburettor replaced the Rolls-Royce one and magneto ignition was no longer fitted but a spare ignition coil was provided. The riveted chassis had rigid front and rear axles suspended by half elliptic springs with hydraulic dampers. Braking was on all four wheels assisted by a mechanical servo with separate rear brakes fitted for the handbrake. Also fitted was the traditional Rolls-Royce radiator with vertical louvres, the angle of which was controlled thermostatically to control engine cooling. Only the chassis and mechanical parts were made by Rolls-Royce. The body was then made and fitted by a coachbuilder selected by the owner.
In the early 1930s, all luxury marques were delivered as rolling chassis to one of many marque-approved coachbuilders for completion. Chassis GGR 26 was bodied by Thrupp & Maberly in a delightful four-door “Sports Saloon” design. Thrupp & Maberly were favoured by royalty and heads of state, and they specialised in exquisite, well-built bodies with elaborate interiors for Rolls-Royce, Bentley, and Humber. The quality of their work was so superior that Sir Henry Seagrave’s Golden Arrow captured the world’s land speed record in 1929, at 231 mph, wearing a streamlined body supplied by this coachbuilder.
In this case our 25/30 was supplied to Thrupp and Maberly and fitted with Sports Saloon coachwork, thereafter being sold via Jack Barlay of Hanover Square to a Ms. M. Inge in Hampshire. The 25/30 was specified with Polished Staybright Chrome fittings, Ace winglamps, Lucas P100 headlamps, and an outside spare wheel carrier.
Our vendor bought this highly original 25/30 in 1971 and has owned it ever since. In current ownership now for over four decades, the 25/30 has been stored carefully and used in conjunction with his other vintage Rolls-Royce motor cars, which are also included in this sale.
This rather handsome and well-proportioned Sports Saloon is offered with its original buff logbook and more recent V5/C document.
