Background

The famed 4 ½-Litre Blower Bentley originated from the fertile mind of Sir Henry Birkin, who was one of the original “Bentley Boys,” as W.O. Bentley’s works racing drivers were known. While Birkin had already won the 1929 edition of the 24-Hours of Le Mans co-driving a Bentley 'Speed Six' with then-Chairman Woolf Barnato, Birkin was convinced that a lighter-weight, supercharged Bentley would prove effective in competition, especially in concert with the marque's renowned reliability. Barnato seemingly agreed, notwithstanding early objections to supercharging from none other than W.O. Bentley. 50 examples were required to homologate the new model for competition, the majority were offered for sale to the public.

With their powerful supercharged engines, reputed to deliver in excess of 240hp, lightweight leather-clad Vanden Plas bodies, and minimalist cycle-type fenders, the 'Blower Bentleys' exuded power, speed, and exclusivity, key elements of the Bentley mystique that continues today. Then, as now, the 'Blower Bentley' represents one of the most desirable and virile British vintage cars ever constructed, and as a result, they are highly prized by their owners and appear only infrequently at public sale. Many have never come to market, remaining locked within the confines of private collections all over the world, where they will likely remain for many years to come.

Answering the call for custom, “tool room” recreations constructed to exceptional, hand-crafted standards, the UK’s Bob Petersen began building faithful, magnificently engineered pre-war Bentley recreations to uncompromising standards of detail and quality.

Overview

This stunning Bentley 4 ½-Litre Blower recreation was hand-crafted by the marque specialists at Bob Petersen Engineering in the UK, and according to recent correspondence with Mr. Petersen, it's the 14th example produced, constructed in 1997 and built on a 1938 Rolls-Royce 25/30 chassis. According to marque specialists, the first twelve examples were commissioned and sold through the renowned London Rolls-Royce and Bentley dealer, Jack Barclay.

Unique details abound, with many of them authentically reproduced by Petersen to exacting standards. Offered in excellent condition, the vehicle displays only the slightest presence of patina, and it is offered in exemplary, collector- and enthusiast-worthy order throughout.

Featuring a lightweight, green leather-clad aluminum-skinned ash body authentically duplicating the period work of Van den Plas of Belgium, this stunning 4 ½-Litre Blower Bentley recreation evokes rich images of motorsports glories and exotic adventures. From the chrome-plated radiator shell to the twin side-mounted and rear spares, racing livery, and green painted wire wheels and blackwall tires, this Petersen Blower includes such correct details as twin ‘Brooklands’ style windscreens, an external emergency brake lever, and a “fishtail” exhaust tip. Visuals are wonderful and convey nothing but the purposeful, race-intended styling and features of a true competition Bentley.

Interior

Richly trimmed in green Connolly leather with matching Wilton wool carpets, this fabulous motorcar includes an engine-turned dash insert and a full complement of period-correct instruments monitoring vital functions. The steering wheel and passenger grab handles are wrapped in white cord and maintain the racing flavor of this amazing Bentley 4 ½-Litre Blower recreation, while the original convertible top appears as if it has never been up - and it probably hasn't!

The 4 ½-Litre overhead-valve straight 6-cylinder engine from a Bentley MkVI was fully rebuilt, 'blue-printed', and modified to drive the supercharger when installed at Petersen, and it's presented in period 1928 correct appearance. Combined with Petersen's custom, hand-built supercharger (made to look like the original Amherst Villiers units) delivers an abundance of power to the modified MkVI 4-speed manual transmission with added overdrive. The chassis is from (and it's registered as) a 1938 Rolls-Royce 25/30, while associated underpinnings faithfully echo those of the 50 original cars, helping to deliver an incomparable and authentic driving experience.

Since acquisition a few years ago, the seller has invested nearly $50k into the car, including an engine overhaul, installation of a new wiring harness, cleaning and re-sealing of the slab-type fuel tank, and fitment of new tires with tubes for a more comfortable ride. More recently, the carburetors and ignition timing were expertly tuned by Chris Kidd of Tired Iron Works in California.

History

As stated above, this mighty 4 ½-Litre Birkin Blower Bentley recreation #1014 was completed in 1998 and built on/registered as a 1938 Rolls-Royce 25/30 chassis GGR64 as pictured in the photo gallery with its original Thrupp & Maberly Saloon body. According to recent correspondence with Bob Petersen, the first owner was from Holland, and it was delivered to them circa 1999-2000. It next went to France, and was in turn sold to the United States, before being bought by the current California owner in 2018. Service and tuning as described above renders it an eminently fitting, tour- and show-worthy recreation of the few Blower Bentley models ever produced some 90-years ago.

Summary

As offered, this amazing motorcar stands ready for shows, tours, and immensely enjoyable drives on your favorite stretch of winding road. Evocative images of exotic locations and of course, the 24-Hours of Le Mans circuit, are conjured with each and every drive.
