Originally built with H.J. Mulliner two-door drophead coachwork, this 1931 Rolls-Royce 20/25 was eventually purchased as a rolling chassis in 2014 and transformed with alloy boattail-style bodywork into a Blower Bentley-style “Dreadnought Special” featuring a supercharged 3.7-liter OHV inline-six. The car also highlights a custom billet camshaft and aluminum cylinder head, twin SU carburetors, a 4-speed overdrive manual transmission with an AP Racing clutch, Andre Hartford friction shock absorbers, cord-bound springs, finned aluminum drum brakes, 19” wire wheels, and red leather upholstery. Accompanied by invoices and photos from its four-year custom build process, this one-of-a-kind Rolls-Royce 20/25 is now being offered for auction out of Belgium.
The car’s original 20/25 chassis is said to have been shortened to a 108” wheelbase to match a 1920s Bentley Green Label 3-liter special. It features an Ashwood frame overlaid by hand-fabricated aluminum panels made by Bespoke Bodywork of Church, Crookham, England. The body is finished in dark green and showcases a louvered bonnet and rocker panels, leather hood straps, a louvered boattail rear end, a single rear-hinged door, dual Monza-style fuel lids, tri-bar headlights, dual Brooklands-style windscreens, a side-mounted exhaust system, and a black tonneau cover. The car rides on red-painted 19” wire wheels with 6.5” Blockley tires.
The cockpit is trimmed in red leather with black carpeting and features a two-person bench seat, an engine-turned aluminum dashboard fascia, and a leather cord-wrapped four-spoke steering wheel on the righthand side. Other accessories include an external gated shifter, analog instrument dials, a door storage pocket, an electrical cutoff switch, Bentley foot pedals, and a chrome door handle.
Featuring a front-mounted Godfrey Marshall K300 supercharger and dual SU carburetors, this 20/25 is equipped with a 3.7-liter OHV inline-six engine. It also features a Fiennes Restoration aluminum cylinder head, a custom Newman billet camshaft, forged pistons, a Sterling Rattler vibration damper, a lightened flywheel, a four-core radiator, an electric cooling fan, and an aluminum gas tank. Power is sent to the rear wheels through an overhauled 4-speed manual gearbox with an AP Racing clutch and a Laycock de Normanville overdrive unit. The suspension includes solid axles, lowered cord-bound semi-elliptical leaf springs, and adjustable Andre Hartford friction shocks. Stopping power comes from mechanically actuated aluminum finned drum brakes.
This sale will include build records, a factory build sheet, and a U.K. registration..
