I NSTRUCTI0i4 in the repair and maintenance of motor vehicles is an important part of Service training. A valuable adjunct to those whose concern it is to impart technical know ledge, in this connection, is constituted by charts, diagrams', and so forth, explaining'motor mechanisms.
A set of wall charts devised for this specific purpose has just been produced by the Nuffield Organization. They relate to Morris vehicles, .-and they are of notably high quality. There are eight wall charts measuring 30 ins. by 20 ins., and they are available, on demand, at 7s. 6d. per set,' which includes' postage. Applications should be addressed to 'the Public Relations Officer, The Nuffield Organization, Cowley, Oxford.

the main feature of Chart No. 2 is a cut-away drawing in perspective of a gearbox. It is supplemented by five explicit diagrams showing how the drives for the four speeds and reverse
' gear, respectively, are obtained, and giving details of the synchromesh clutches incorporated in top and third ratios.
Three illustrations of components figure in Chart 3, namely, a-shaded section of an S.U. carburetter, a perspective picture of a clutch with the various parts separated, but arranged, .otheria their respective positions, and a cut-away view of a water pump.
The subject of the, fourth chart is the electric components, and it shows a perspective drawing cif. ,the ignition group of units, together with a drawing of a distributor with the .top lifted to expose the electrodes inside it and to display the rotor and contact breaker.

No. 5 deals with the steering gear. It comprises a cut-away -view, of the complete steering column,' a sketch of the steering assembly (including the front axle and hubs) and a detail drawing of the mechanism of the steering box.
Chart 6 explains the brake layout. The hydraulic and mechanical connections are indicated in full lines on a plan drawing of a chassis in dotted lines. Supplementing this diagramm‘ticrepresentation is a section of a mastercylinder unit with two detail views of an expander cylinder.
Finally, on Chart 7, which is headed " rear axle assembly," is a first-class cut-away perspective drawing explaining the construction of a rear axle. It shows the final drive, the differential and the hub, including the brake, so that every working part can be understood. There are actually two drawings of, the last item taken from two viewpoints
