You’d never be in fear of outbraking the car behind, though: the four-wheel stoppers lack any real bite, a trait afflicting many cars with this early technology.
Morris Garages in Oxford went from a sales and servicing firm to a successful marque in itself
But the Super Sports was only part of Cecil Kimber’s armoury for carving out MG’s more enthusiast image.
Competition success was key, and to achieve that with the Morris-based chassis meant looking at alternative engines.
The sidevalve Oxford ‘four’ had been developed from an American design by Hotchkiss in its English factory.
An overhead-valve unit had been tested but never used, and discarded at the Morris engine works in Coventry, where Kimber found it.
MG Old Number One’s (closest) unique, experimental overhead-valve ‘four’ gives it a livelier edge, aided by the skimpy, lightweight body
The 1548cc unit had its camshaft mounted low in the block, operating in-line valves with double springs via a system of tappets, pushrods and rockers.
Carburetion was originally by a single SU (it now has a more modern 1¼in item), with fuel pressurised by hand from the cockpit.
The ‘new’ engine was mated to the standard, but tough, Morris three-speed ’box.
Kimber’s plan was to install this drivetrain in a one-off competition car, based on a bullnose Cowley chassis, and enter it in the 1925 Land’s End Trial.
MG Old Number One has four-wheel brakes
Carbodies designed and manufactured a lightweight body and the chassis was modified, with the rear frame cut off and replaced by new rails that curved over the rear axle to locate splayed rear springs.
The front semi-elliptic springs were retained, while those at the rear were simply mounted to the chassis, without supporting three-quarter elliptics.
Standard three-stud hubs were used, to which tall wire wheels with 7.1-90 tyres were fitted.
Braking was by stock Morris drums and, as with the Super Sports, the steering column was lowered.
MG Old Number One’s snug cockpit is fronted by a handsome, engine-turned dashboard
Reportedly costing just £279 to build, Old Number One repaid MG’s investment many times over.
After winning a Gold Medal in the Light Car Class at Land’s End, Kimber sold the car to a friend for £300.
Soon after it was seen towing a pig-food trailer, then almost ended its days in a Manchester scrapyard.
Had it not been spotted by an MG employee in 1932 and bought for £15, this historic car might have been lost.
After returning to Abingdon, it was rebuilt and its original primer-grey coachwork was painted red.
MG Old Number One’s 1.5-litre motor likes to rev
Given the ‘Old Number One’ moniker, it was used for promotional purposes, with a further restoration taking place in 1950.
Today the car is a proud exhibit at the British Motor Museum in Gaydon, Warwickshire.
We’re with Old Number One just a week after its return from recreating Kimber’s run up ‘Old Blue Hills Mine’.
Like the Super Sports, the racer is boat-tailed, but there the similarities end.
Daintily proportioned, with tiny, angular mudguards, its bullnose grille is the only visual link with its modified Morris underpinnings.
Old Number One is probably the best-known early MG
You sit low on slim leather chairs, the riding mechanic mounted a few inches back from the driver.
There’s no windscreen, with the scuttle curved up to deflect wind and flies; Kimber and his man have their faces partially obscured by it in a photograph from the trial, and the same goes for me as I peer over the lip to get a better view.
MG added extra dials across the engine-turned dash, including a tachometer, and pressure gauges for oil and fuel.
You find yourself close to a medium-sized three-spoke wheel and, like in the Super Sports, the pedal positions are conventional, with the wand-like gearlever centrally positioned. Old Number One is a joy to drive.
MG Old Number One’s elegantly tapering tail
The exhaust sounds unbaffled, rewarding with a crisp and urgent timbre from the experimental ‘four’.
The controls are light, with the single-plate cork clutch surprisingly progressive as you pull away.
The steering feels 50% quicker than the Super Sports’, which, combined with restricted vision, means corner apices are a hit-and-miss affair to start with.
Body control is tight and secure, and the little car thrives on revs, to the point where I’m changing up early to prevent any damage.
A glitch with the brakes means slowing requires more effort than I’m told it usually does, but it doesn’t spoil the enjoyment of what was clearly a talented standard-bearer for the freshly minted MG brand.
I’m not sure how Kimber would have viewed the Chinese-built creations that now wear the octagon, but I hope today’s company realises that there was life before the MGB.
