NO fewer than eight goods-carrying vehicles and chassis are to be seen on the stand of the British branch of this well-known French maker. Taking them iu order of pay-load capacity, the first is the two-tonner, which is shown complete with a drop-sided body and

priced at £410. The 20 h.p. engine has four cylinders with a bore And stroke of 90 mm. and 130 rem. respectively. The cylinder block is east in one with the top portion of the crankcase, whilst the detachable head is fixed by studs to the top of the block. The crankshaft is carried in three bearings and the gudgeon pins are locked in the small ends of the connecting rods by means of setscrews. The valves are ranged on the near side of the engine, which is governed to a speed of 2,606 r.p.m. A four-speed gearbox is mounted in unit fashion with the engine, a plate clutch being interposed. .

A•divided propeller shaft, with a selfaligning ball race at its centre, carries the power to the overhead-worm tear axle, the springs of which take both torque and driving stOesses. This machine has a 13-ft. wheelbase and a 5-ft. 3i-in. track.

Known as the type V.K.R. is a 3-ton chassis with a 22.3 h.p. four-cylindered engine.. In this ease the bore and strdke • are 95 mm. and 130 tom. respectively. This model differs from the preceding one in that the four cylinders are cast in two blocks and have separate detach'able heads. The valves are of the side. by-side variety, and pressure lubrication is tiSed together with a special oil-cool ing sump. A combined starter and dynamo is driven by silent chain from the crankshaft.

A. steel bumper bar is built into the front end of the chassis frame. SusPension is by semi-elliptic springs which also serve to take the torque and the drive of the rear axle. Berliet mechanical-servo braking is used for all four wheels. In this design a rotating plate is brought into contact with a stationary one ; to the latter are connected. through the medium of chains, the two brake-operating rods. When the stationary plate is dragged around by being brought into contact with the rotating one, the brakes are applied with considerably more power than would be Possible by physical effort.

Two 5-ton tipping wagons are shown. Both have chassis of the C.B.A.C. pattern with an engine of 30 h.p. having

four cylinders, side-by7side an

engine-speed governor, .pressure•lubrication, magneto ignition and Zenith carburetter. A multiple-plate dry clutch transfers the power to the four-speed separately mounted gearbox, final transmission being by chains. One exhibit is fitted with an all-metal body and a single-way tipping gear driven from gearbox. In this case the body is raised by wire ropes running over pulleys. The other tipper has a longer wheelbase, a narrower track and Woods Hydraulic tipping gear.

In many respects the 5-ton longwheelbase model has a similar specification to that of the tipping wagons. In this instance, however, a drop-aided lorry body is mounted upon a chassis having a wheelbase of 17 ft. 4 ins. For those who require a chassis for highspeed work. the 4-5-ton live-axle' model is marketed. This has a double-reduction gear in the back axle, a wheelbase of 13 ft. 11 ins., and servo braking. It is shown in chassis form.

A six-cylinde red. (1.10 mm. bore by 140 tnm, stroke) engine is used in. the tractor unit and in the rigid six-wheeler. The valves are ranged on the near side of the power unit, which drives a fourspeed-and-reverse gearbox, from which the drive is taken by chains to the rear axle. . In the case of the six-wheeler only the forward axle of the bogie is driven. The wheelbase of the tractor unit is 12 ft. 4 ins., but that of the sixwheeler is 16 ft. 4 ins., measuring from the hubs of the front wheels to these of the forward 'axle of the bogie,
