About Mr J40
Specialist knowledge, focused solely on the Austin J40 pedal car.
A dedicated Austin J40 specialist
Mr J40 is a specialist business dedicated exclusively to the Austin J40 pedal car. Our work centres on preservation, restoration, parts manufacture, and historical reference for one of the most recognisable pedal cars ever produced.
By focusing on a single model, we are able to offer a depth of knowledge and practical experience that goes beyond general classic or vintage toy restoration.
Experience and approach
Our involvement with Austin J40 pedal cars spans many years of hands-on work, including full restorations, sympathetic repairs, parts development, and research into original specifications and production details.
Every pedal car is approached individually. Originality, condition, and long-term integrity are always considered before work is undertaken, and advice is offered honestly and without obligation.
What we do
• Restoration of Austin J40 pedal cars, from full rebuilds to sympathetic repairs
• Manufacture and supply of reproduction parts to original patterns
• Technical advice and support for collectors and restorers
• Heritage Certificates providing documented reference information
• Sourcing and supply of Austin J40 pedal cars where appropriate
Authenticity and attention to detail
Authenticity is central to all work undertaken. Original factory references, surviving examples, and accumulated experience inform decisions on finishes, components, and detailing.
Where original parts cannot be retained, reproduction components are manufactured or selected to closely reflect original materials, proportions, and appearance.
Who we work with
We work with collectors, restorers, and enthusiasts in the UK and internationally. Some clients are long-term collectors, while others are first-time owners seeking guidance and reassurance.
In all cases, advice is practical, informed, and tailored to the individual pedal car rather than a generic process.
Our philosophy
Austin J40 pedal cars are historical objects as well as collectable items. Our aim is to preserve their character, accuracy, and longevity, whether through careful restoration, sympathetic repair, or informed ownership.
If you would like to discuss an Austin J40 pedal car, restoration, or related services, we are always happy to advise.
