Made in the Midlands: W.H. Tildesley — The Willenhall Forge Hidden Inside Britain’s Great Motorcycles
A rider could spend years admiring British motorcycles without ever noticing the name W.H. Tildesley. It was not normally painted on the petrol tank, displayed on a dealer’s sign or printed prominently across a racing programme. Yet inside motorcycles carrying some of Britain’s most famous badges were pieces of metal shaped by the company’s workers in Willenhall.
Connecting rods, rocker arms, levers, footrests, sprockets and frame fittings were not glamorous showroom accessories. They were parts expected to tolerate heat, vibration, repeated loads and roads that were often far rougher than anything a restored classic encounters today. If one failed, the reputation damaged belonged to the motorcycle manufacturer—even when the component had originated elsewhere.
That makes W.H. Tildesley an important part of the Made in the Midlands story. It reveals an industry that did not consist simply of self-contained factories building every part under one roof. It was an interconnected regional ecosystem in which specialist firms supplied the skills, materials and components that complete motorcycle manufacturers needed.
A Willenhall business older than the British motorcycle industry
W.H. Tildesley traces its establishment to 1874, before the motorcycle had emerged as a practical form of transport. Willenhall was already part of the Black Country’s dense metalworking landscape, an area where generations had developed expertise in locks, tools, presswork, castings and forgings.
Drop forging involves heating metal and forcing it into shaped dies, using heavy machinery to produce a component with the required form and strength. It is physically demanding work, but it is not crude work. Correct temperature, die design, material flow and finishing all matter. A forging intended for a highly stressed engine component has to be consistent, because imperfections can become failures once the engine is running.
The company’s surviving records give the story unusual authority. W.H. Tildesley says its drawing archive dates from 1908 and documents more than a century of production at Willenhall. Rather than relying solely on old advertisements or memories recorded decades later, researchers can examine drawings created for actual jobs.
Those pages are industrial evidence. Dimensions, dates, customer names and component forms show how one regional supplier became connected to manufacturers across the country.
The journey from a drawing to a motorcycle
A finished forging begins long before hot metal reaches a hammer. A required part must be understood and drawn. Tooling and dies have to be designed so that the heated material flows into the right shape. The forging may then require trimming, machining, heat treatment or further finishing before it becomes ready for the customer.
Each stage depended on people with different skills: draughtsmen, toolmakers, die sinkers, furnace workers, hammer operators, inspectors and machinists. The dramatic moment was the blow that shaped glowing steel, but the success of the part depended on all the quieter decisions made around it.
Once delivered to a motorcycle manufacturer, the component lost much of its visible identity. A connecting rod became part of a Sunbeam engine. A rocker arm belonged to a Triumph or Ariel. A footrest became something the rider used without wondering who had heated, struck and inspected the steel.
This invisibility helps explain why component makers rarely receive the public recognition given to motorcycle brands. Their success was measured partly by becoming unnoticed. A correctly made part performed its job for years while the name on the tank received the credit.
From Sunbeam to AJS: the Midlands network in metal
W.H. Tildesley’s archive demonstrates how widely that contribution spread. Records for John Marston Ltd show forged Sunbeam components produced between 1919 and 1935, including connecting rods, rocker shafts, flywheels, handlebar levers, footrests and lugs.
For A.J. Stevens & Co, the company records more than 100 unique components supplied between 1923 and 1940. These covered forks and fork ends, gearing, engine parts, levers and links. The relationship places the Willenhall forge inside the story of one of Wolverhampton’s most significant motorcycle manufacturers.
The significance lies not only in the quantity of different parts. It lies in the concentration of expertise. Sunbeam, AJS and the forge were operating within the same wider industrial district. Problems could be discussed, drawings revised and production relationships maintained without components travelling halfway around the world.
This local concentration was one of the Midlands motorcycle industry’s greatest strengths. It enabled relatively small manufacturers to obtain specialist components without carrying the cost of producing everything themselves. It also allowed knowledge developed for one part of the engineering economy to support another.
Matchless, Triumph, Ariel and the national reach of a Midlands forge
The customer network extended well beyond nearby Wolverhampton. W.H. Tildesley says it produced more than 200 unique components for Matchless between 1919 and 1965. They ranged from connecting rods, valves and rocker components to clips, fasteners and frame trim.
Its Triumph records cover work from 1935 to 1973, including engine connecting rods, valve rocker arms, footrests, operating levers and frame components. Ariel records identify rocker arms, sprockets and related engine parts supplied between 1937 and 1952.
Velocette was another major heritage customer. The company’s archive identifies numerous forged parts for the MOV, MAC, MSS and KTT families, as well as 33 forged components associated with the post-war LE. These records give a useful new dimension to the Velocette story. The motorcycles were manufactured at Hall Green, but parts of their physical strength began in Willenhall.
The map of British motorcycle manufacture therefore looked less like a row of isolated factories and more like a web. Famous marques sat at visible points, while specialist businesses connected them through steel, rubber, electrical equipment, carburettors, bearings and countless other necessities.
The strength and vulnerability of the component system
This network allowed motorcycle manufacturers to draw upon excellent specialists. It could be efficient, flexible and highly innovative. A smaller marque did not need its own large forging department if a company such as W.H. Tildesley could supply the necessary parts.
The same system could also create vulnerability. A motorcycle factory might possess frames, engines and orders yet still be unable to complete machines if one essential component was delayed. Material shortages, transport problems, industrial action or competing wartime priorities could affect several manufacturers through the same supplier network.
It would be too simplistic to blame the structure itself for the later decline of the British motorcycle industry. Japanese manufacturers did not succeed because of one convenient explanation, and British factories faced challenges involving investment, management, product planning, quality, industrial relations and changing customer expectations.
Nevertheless, component suppliers are essential to understanding how the industry actually functioned. The finished motorcycle was the final result of numerous businesses meeting their obligations at the right time. Production depended on relationships as much as machinery.
Forging for war as well as motorcycles
Like many Midlands engineering businesses, W.H. Tildesley’s history extends into wartime production. Its archive contains records for components connected with weapons and military aircraft, including work associated with Rolls-Royce Merlin and Griffon engines, the Bristol Beaufighter and Blackburn aircraft.
This demonstrates how engineering capacity was redirected when national priorities changed. The same core knowledge of materials, dies and controlled forging could serve motorcycle manufacture in peacetime and military requirements during war.
For workers, this was not an abstract change of market. It meant different jobs, heavier pressure and the knowledge that what left the factory might become part of an aircraft or weapon rather than a civilian machine. It also meant that the post-war motorcycle industry inherited people and facilities shaped by years of urgent production.
Britain emerged from the Second World War with enormous demand for transport and exports, but also with material controls and worn industrial equipment. Specialist firms had to satisfy customers while managing shortages and national priorities. That wider context is important when we look back at the celebrated post-war years of British motorcycles.
The archive that keeps making parts
W.H. Tildesley is not simply the subject of a closed history. The company still operates from Clifford Works in Bow Street, Willenhall, and its heritage division uses modern engineering methods to reproduce obsolete components.
That work creates a direct link between an old drawing and a motorcycle being restored today. Where an original part is unavailable, a surviving drawing or physical sample can help engineers recreate its form, develop tooling and produce a new forging.
This is heritage in a practical sense. A drawing is not preserved merely because its paper and handwriting are interesting. It can help return a machine to the road. Modern digital methods do not erase traditional knowledge; they can give it another working life.
There is also something appropriate about a Willenhall firm continuing to manufacture rather than existing only as a museum display. The environment, processes and safety standards may have evolved, but the underlying purpose remains recognisable: shaping metal into a component that must perform reliably.
The workers behind the parts nobody noticed
Company records tell us what was made and for whom. They cannot, on their own, fully describe what the work felt like.
A complete account needs the voices of people who understood the heat, noise, repetition and judgement of forging. It needs to know how apprentices learned, how experienced workers recognised the correct temperature and how a drawing was translated into tooling. It should also ask how modern employees view the old books that document jobs completed by earlier generations at the same works.
This is where a future visit could deepen the story. Original photographs of the works, drawings and surviving tools—and a conversation with someone responsible for the archive or production—would turn an important industrial record into a living human account.
Until then, the existing evidence already makes one point clear. Many motorcycles remembered as products of Birmingham, Wolverhampton or London were also products of Willenhall. Their famous names were supported by people whose own company name remained largely hidden.
Made in the Midlands meant more than a badge
The easiest way to tell British motorcycle history is marque by marque. It is also incomplete.
A motorcycle was an assembly of ideas, materials and labour moving between businesses. W.H. Tildesley’s archive allows us to follow some of those connections with unusual precision. Sunbeam, AJS, Matchless, Triumph, Velocette and Ariel appear not merely as separate manufacturers but as customers drawing upon a shared tradition of specialist manufacture.
The Willenhall forge deserves its place in Made in the Midlands because it changes where we look. Instead of focusing only on the badge, it asks us to consider the connecting rod turning inside the engine, the rocker arm opening a valve and the footrest carrying a rider’s weight.
Those parts rarely attracted attention when they performed properly. More than a century later, the drawings and the surviving company finally allow us to recognise the people and place behind them.
