That works both ways and applies to everything. The less complex an article, the easier it is to make, the cheaper it may be sold, and therefore the greater number may be sold.
It is not necessary to go into the technical details of the construction but perhaps this is as good a place as any to review the various models, because "Model T" was the last of the models and the policy which it brought about took this business out of the ordinary line of business. Application of the same idea would take any business out of the ordinary run.
I designed eight models in all before "Model T." They were: "Model A," "Model B," "Model C," "Model F," "Model N," "Model R," "Model S," and "Model K." Of these, Models "A," "C," and "F" had two-cylinder opposed horizontal motors. In "Model A" the motor was at the rear of the driver's seat. In all of the other models it was in a hood in front. Models "B," "N," "R," and "S" had motors of the four-cylinder vertical type. "Model K" had six cylinders. "Model A" developed eight horsepower. "Model B" developed twenty-four horsepower with a 4-1/2-inch cylinder and a 5-inch stroke. The highest horsepower was in "Model K," the six-cylinder car, which developed forty horsepower. The largest cylinders were those of "Model B." The smallest were in Models "N," "R," and "S" which were 3-3/4 inches in diameter with a 3-3/8-inch stroke. "Model T" has a 3-3/4-inch cylinder with a 4-inch stroke. The ignition was by dry batteries in all excepting "Model B," which had storage batteries, and in "Model K" which had both battery and magneto. In the present model, the magneto is a part of the power plant and is built in. The clutch in the first four models was of the cone type; in the last four and in the present model, of the multiple disc type. The transmission in all of the cars has been planetary. "Model A" had a chain drive. "Model B"
