The current owner of 6 G II has dedicated many years to its research and there is a large file of correspondence detailing how the cars history has been pieced together. Rolls-Royce specialists have been tasked with the identification of this car and subtle differences on this chassis compared to later production examples; prove that this was indeed an experimental car. John Fasal, author of 'The Rolls-Royce Twenty' describes the 6 G II as the earliest Twenty. Initially acquired by the current owner in 1982 as a dismantled and unidentified chassis, its significance was not initially appreciated, so sold on again two years later. Some fourteen years later the same Rolls enthusiast purchased the chassis back, still in the same state, and began to realise that there were numerous differences between it and the several other early 20hps in his possession. It displayed many early characteristics but in addition had some totally unique features.
There are no luggage support brackets, which are on all other 20 hp cars; the holes for the rear friction shock absorbers are uniquely positioned on the side of the frame; the chassis radiator cross member uses countersunk rivets on the top off side (only) to fix it to the chassis. All other rivets are of the usual Rolls-Royce round head type; both rear spring hangers have been extended and modified, presumably for some type of testing; each of the six body mounting brackets, F51758, is fixed to the chassis with only three bolts, not the four bolts as used on all other cars; the chassis is a quarter of an inch narrower than the standard chassis.
These six features point to a prototype. The owner also realised that the works chassis number is stamped on all three speed 20hp cars, on the rear near side frame. This works number is also recorded on all chassis cards held at The Hunt House. Due to corrosion, UV light and sophisticated detection equipment was used to see if the chassis was originally stamped 10, whereas the first production chassis 40G1 was the works number 21. By a series of deductions and eliminations, the chassis was identified as 6 G II. Having established the early heritage, the owner added a 1922 engine (G171), gearbox, radiator with early type shutters, starter, axles and beaded edge wheels so that the chassis is complete but not running. (Engine numbers were never recorded on experimental cars). Most of the original patination has been preserved without restoration.
Seven prototypes were built, the latter six known as Goshawk II and the owner of 6 G II has identified that due to the D rake of the steering, this chassis must be the one originally registered CH 2927 and clothed with open touring coachwork by Mulliner, and along with 7 G II, were known as Cinderella cars. This original registration number has been recovered and it has been ascertained that engine no. G171 is almost contemporary to the vehicle. A truly unique opportunity to acquire an important piece of motoring history.
