CONSTRUCTION.

The rear wheel arches are of pressed sheet steel spot welded to the side panels of the body and attached to steel channel section extensions of body bottomsides. The rear pillars are also attached to the wheel arches by means of pressed steel plates.

The windscreen opening is surrounded by steel pressings which must help to make the front of the body very rigid.

The windscreen itself is fixed which further helps to secure rigidity.

The door of the luggage locker is framed up in the usual way and, of course, panelled in steel. It has concealed hinges at the top and a pair of sliding supports to maintain it in the opened position. It has a wide water gutter round the door opening with a Sorbo rubber seating, presumably to keep out water and dirt, but dust appears to find its way inside the locker along the bottom edge of its door.

WINGS.

These are of semi-streamlined design andof 18 S.W.G. steel. In spite of the fact that they have no stone guards, there are no signs of starring or of other damage by stones thrown up by the tyres, nor do they appear to have rusted.

The front wings are supported on strong stamped steel stays about 4" wide, the rear stays to the front wings are of the elbow pattern bolted below the spare wheel wells.

There are stays supporting the outer valances to prevent vibration.

The rear wings are bolted into the wheel arches.

The running boards are of steel covered with moulded rubber pads; each is supported by pressed steel stays and attached to the front and rear wings. Although there are only two stays for each step, each stay is strengthened by a support from the top of the chassis which makes it very strong.

MOUNTING.

The body is mounted on massive rigid brackets through
