These were editions from the 33003 series of driver's manuals.
In 1961 a new version was issued covering all Blue Square vehicles - BR 33003-92. A companion to this was a "Preparation and Disposal" booklet BR 33003/211.
In 1968 the booklets were replaced by a three part set for Blue Square vehicles Mechanical Transmission):
BR 33003/247 1 - General Data And Equipment
BR 33003/248 2 - Driving Instructions Including Standard Preparation and Disposal Duties
BR 33003/249 3 - Fault Finding Data and Charts
And for Blue Square vehicles (Hydraulic Transmission:
BR 33003/250 1 - General Data And Equipment
BR 33003/251 2 - Driving Instructions Including Standard Preparation and Disposal Duties
BR 33003/249 3 - Fault Finding Data and Charts
I do not have a copy of the first two, and the third was shared with the mechanical vehicles.
These are believed to be publicity images distributed by Cravens, and probably taken circa December 1959, the date the vehicles were delivered.
