THE SIX-CYLINDER MATHIS

THE SIX-CYLINDER MATHIS—continued.

by the intended alteration from km.p.h. to m.p.h. for the instrument.

A further improvement would be some simple form of clamp to secure the wheel jack, pump and other articles carried loose in a space behind the driver’s back rest. These things rattle about and give one the impression that the wings have worked loose.

It would appear that the right kind of oil for the engine has not yet been determined, for that used for our tests did not give complete satisfaction, and when drained out after a 250 mile run, appeared to have lost most of its lubricating properties.

Thus it will be seen that our criticisms are not of a very serious nature and for the most parts are details unlikely to be noticed by anyone who is not hypercritical.

An Inspection of Mathis Components.

As there seems to be a general impression among intending purchasers concerning the supposed flimsiness of some of the smaller sports cars, we made a special point of examining a selection of the components held in stock by the Atom Motor Company at Hampstead.

These comprised all sorts and sizes of spares, including crankshafts, pistons, gears, and the like. It may be said at once that the quality of the material and the workmanship are very good, all the machine work being well finished to close working limits. Another interesting point observed during our inspection of the parts was the high factor of safety noticeable in the components, that is to say, there was no sign of the weight having been cut down to so fine a limit that wearing quality would be endangered. The matter of engine balance appears to have been studied, but those who desire to amuse themselves by further efforts in this direction will find enough metal to play with, which is an important detail when tuning up an engine for the highest pitch of perfection. In all details of the design and construction, the Mathis bears

evidence of having been produced by a firm with wide experience of larger cars and in many respects this model may be described as a large car in miniature.
