The Majestic Major was a large, staid, luxury saloon car, but despite its weight it could out accelerate a good many sports cars of the period. This ability came from its superb 4.5 litre engine, illustrated here in cutaway form. The smaller 2.5 version was more numerous, fitted into the SP250 sports 2 seater, and a Jaguar bodied saloon as well. The brilliant Edward Turner was responsible for the engine design as well as the famous Triumph speed twin motorbike engine. The illustration was drawn in pencils onto fine illustration board.

This drawing was published in Classic Mechanics magazine to accompany a feature. In the early seventies the financially struggling Norton company commissioned Keith Duckworth (of Cosworth fame) to design a new engine in an effort to compete with the influx of  japanese competition. The new design was also to be available in a road going bike using a single SU carburettor, but the project never came to fruition because the funds just couldn’t be raised to finish the development. At 750cc the configuration was derived by adopting two cylinders based on their famous DFV racing V8, and the engine was a success. What a pity it never realised its potential as an example of British design excellence.








Although most of my work is commission-based, I am happy to work as a sub-contracted 3D specialist with your creative and technical teams. I realise that hand-made finescale modeling requires a wide array of skills and talent including pen&ink illustrations, traditional sign painting, model scenery props and foliage fabrication, photo-realistic finishes and patinas for natural and man-made historic recreations and accurate research methodologies, process simulations, concept testing and revisions that underpin high-fidelity model-making.

Bambrick Studio are also very adept at fabricating full-scale modeling for commercial and private collection pieces of furniture, product samples, prototypes, concept validation test rigs, product recreations for photo-shoots, presentation models, small batch manufacturing in many materials and process including plastics, tube & sheet metals, castings and secondary processes including finishes, sub-assemblies, packaging simulations and production flat-packing.
