In 1949, Bristol built a revolutionary new chassis called Bristol LD LODEKKA which allowed normal highbridge type bodywork to be fitted whilst the overall height was that of a standard lowbridge type double-decker. This was achieved by splitting the transmission, using a separate prop shaft for each pair of rear wheels, thus allowing the chassis frame to be lowered.
A second prototype was built in 1950, both of these having Bristol A V W engines of 8.1 litres capacity. The first production models appeared in 1953, these having been modified in the light of experience gained from the two prototypes. Having a wheelbase of 16ft 81/2in, a choice of engines was offered, these being
a Garnder 5LW or 6LW oil engine or a Bristol A V W 6-cylinder unit, and chassis so fitted were classified LDSG, LD6G and LD6B respectively.
In 1957 the Bristol A V W engine was superseded by a larger 8.9 litre unit of the BVW type. A choice of 4 or 5-speed constant mesh gearbox was offered, whilst the brakes were of the triple servo vacuum type. Although production of the LD model ended in 1959, a further 162 were built between 1959 and 1961 for the Scottish Bus Group. In all, a total of 2,193 of this model were built plus the two prototypes, and all were fitted with ECW bodywork.
