The Unrivalled Expertise in Smiths Gauge Restoration
Among the pantheon of classic car instrumentation, Smiths gauges hold a particularly revered place. Synonymous with British automotive heritage, these instruments graced the dashboards of countless iconic vehicles, from humble family saloons to high-performance sports cars. Their intricate design and robust construction were state-of-the-art in their time, but decades of use, environmental exposure, and the natural degradation of materials can take their toll. Restoring a Smiths gauge is not merely a repair; it is a highly specialised skill that demands an intimate understanding of their original mechanics and design.
Our technicians possess many years of dedicated experience in this intricate field, providing a service that consistently meets the highest standards of quality. This depth of experience is crucial because each Smiths speedometer, indeed each instrument, presents its own unique challenges. The internal mechanisms, delicate springs, tiny gears, and sensitive magnetic movements require a touch that only comes from extensive hands-on work with these specific units.
Manufacturing Obsolete Parts: A Cornerstone of Restoration
One of the most significant hurdles in restoring older speedometers and gauges is the scarcity of original replacement parts. Many of these components have been out of production for decades, making it virtually impossible to source them through conventional channels. This is where true specialisation shines. With access to the original drawings and tooling of the Smiths Ranges of Instruments, coupled with a fully equipped workshop, we possess the unique capability to manufacture replacement parts that are no longer available. This isn't just about making a part fit; it's about recreating components to the exact specifications, tolerances, and materials of the original, ensuring authenticity and longevity. This capability is absolutely vital for a comprehensive restoration, allowing for the repair of even severely damaged or incomplete units without resorting to compromises that would detract from the instrument's original integrity.
Precision Calibration: Ensuring Accuracy and Reliability
Beyond mechanical repair and aesthetic restoration, the accurate functioning of a speedometer hinges entirely on precise calibration. An instrument that looks perfect but reads incorrectly is of little practical use and can even be dangerous, leading to speeding fines or inaccurate mileage recordings. Our skilled instrument mechanics utilise specialised equipment specifically designed for the intricate process of speedometer calibration. This equipment allows for meticulous adjustments, ensuring that the instrument provides readings that are as accurate as when it first left the factory.
To achieve this level of precision, we require specific calibration details from you, the vehicle owner. These details, often found on a dedicated speedometer calibration page or within your vehicle's service manual, are crucial. They provide the necessary parameters – such as tyre size, final drive ratio, and gearbox output – that dictate how your speedometer should be configured to accurately reflect your vehicle's speed. Without these precise details, even the most advanced calibration equipment cannot guarantee perfect accuracy. The collaboration between our technicians and the vehicle owner in providing this vital information ensures that the calibrated speedometer is perfectly tailored to your specific classic car.
Comprehensive Instrument & Dashboard Repair for All Classic Cars
While Smiths gauges are a speciality, our expertise extends far beyond them. We offer a comprehensive instrument repair and calibration service for a wide array of vintage and classic cars, not exclusively limited to popular marques like Morgans. Whether your dashboard features Veglia, Jaeger, AC, or other period instruments, our service is carried out to the highest standard. A malfunctioning dashboard or inaccurate instruments can significantly detract from the driving experience and even the value of your classic vehicle. Don't let these crucial components let your vehicle down!
Our commitment to quality is underscored by a one-year guarantee on all instrument repairs and calibrations. This warranty provides peace of mind, assuring you that the work performed is durable and reliable. For customers wishing to have their own original units restored, the process is straightforward: simply send them to our workshop for a professional, meticulous service. This approach ensures that the original character and provenance of your vehicle are maintained, which is often a critical factor for classic car enthusiasts and collectors.
The Restoration Journey: From Assessment to Perfect Functionality
Every speedometer and indeed every instrument cluster that arrives at our workshop undergoes an individual, thorough assessment by our experienced technicians. This initial evaluation is a critical step. It allows us to diagnose all underlying issues, from mechanical wear to electrical faults, and to identify any missing or damaged components. Following this detailed inspection, we will advise you on the best options available for restoring your instrument to full working order. This might involve simple repairs, the manufacturing of new parts, complete internal overhauls, or a combination of services.
The goal is always to provide a solution that not only restores functionality but also preserves the historical integrity and aesthetic appeal of the instrument. We understand that each classic car, and thus each instrument, has its own story and requirements. This personalised approach ensures that the restoration plan is perfectly aligned with the needs of your vehicle and your expectations.

Why Professional Restoration is Paramount
Attempting to repair complex classic car instruments without the requisite knowledge, tools, and parts can often lead to further damage, rendering the unit irreparable. Professional restoration offers several key advantages:
- Accuracy and Reliability: Ensures instruments provide precise readings, crucial for safe driving and legal compliance.
- Preservation of Originality: Utilising original drawings and manufacturing period-correct parts maintains the vehicle's historical authenticity.
- Enhanced Aesthetics: Restored instruments elevate the interior appearance, contributing significantly to the car's overall presentation.
- Increased Vehicle Value: Fully functional and beautifully restored original instruments can significantly enhance a classic car's market value.
- Long-Term Durability: Professional repairs and the use of high-quality, often custom-made, parts ensure the longevity of the restoration.
Comparative Analysis: Professional Restoration vs. DIY Attempts
While the allure of a DIY project is strong for many classic car owners, the complexity of instrument repair often warrants professional intervention. Below is a comparative table highlighting key differences:
