The 15-ft. 4-in.-wheelbase model displayed has a Gardner 6LX 10.45-litre 150-b.h.p. oil engine which can, for use in passengei vehicles, be &rated to develop 125 b.h.p. at the same maximum speed of 1,700 r.p.m. In the Wulfrunian it drives through a fluid coupling to a Guy semi-automatic four-speed gearbox with forward ratios of 4.2, 2..38, 1.59 and 1 to 1, • The rear. axle is a double-reduction unit with a ratio of 5.6 to 1. A drawing of the completechassis appears on page 299.

The Other fotir exhibit's are goods vehicles. The extent of the Guy eight-wheeler range is demonstrated by a Warrior light eight-wheeler and a heavy-duty Invincible export chassis. The Warrior .has a wheelbase of 17 ft. 9 in. and is powered by an A.E.C._ 7.7-litre engine developing 112 b.h.p. at 2,000 r.p.m. This drives the leading axle of the rear bogie (a two-speed unit) through a five-speed synchromesh gearbox. Air-hydraulic brakes are fitted and the Warrior now has 1-ft.-. deep chassis side members.

It has a Gardner 6LX engine and a novel 12-speed transmission made up of. a six-speed constant-mesh gearbox behind which is a two-speed synchromesh auxiliary box.
