“And all the time the BD is working he has to bear in mind the possibilities of producing in sheet steel the curves he is outlining.
“For a good many reasons connected with visibility and accessibility, the narrowing down of the heavy mass of a saloon body to a fine front, whilst not forgetting that the motoring world is still a trifle ‘radiator-conscious’, causes the treatment of the front end to become one of the most difficult parts of the design. For that reason, the front end of the model is often made detachable, and a series of different front ends can be applied.
“When at last the BD has satisfied himself, the steel-pressing expert has given his blessing and the body-engineering chiefs have approved the main details, the sample models are submitted to the directors.
“Possibly every point they have in mind is not completely met and further modelling is necessary. In the end, a model is selected for development to the next stages.
“A preliminary set of full-size scale drawings is prepared, from which a full-size ‘mock-up’ model will be made. It is made of timber, in blocks so put together that parts can be removed or reshaped.
“When the mock-up has been gone over with a fine-tooth comb by everyone concerned, the heavy guns come into action.
