Found this in the 1955 Hawk:-
TRIALS TROOP was formed in October, 1953 to conduct War Office Use r
Trials of two of our latest tanks . The arrival of the first tank was a grea t
event. Most of Tripoli was at the docks to see it unloaded . The journey to
Sabratha was a triumphant procession, with policemen clearing the road s
before us and a Field Security sleuth warding off the beautiful spies .
The first few weeks were spent finding out how it worked, and we also
acquired a Centurion, which was to follow us around for comparison purposes .
We then spent three weeks on the Gefara Plain and a lot was learned b y
everyone. Shortage of spares reduced our running, and many days and night s
were spent digging in . After Christmas we tried the tank out on some reinforcements
and selected Tpr . Wood as a driver. We also acquired Tpr.
Hoddinott, who became our ace welder, producing many excellent but unauthorised
modifications . In February, the second tank arrived and we wen t
out to the plain for good . The private army had grown and we now had two
3-tonners, a dozer, and a water cart with those most reliable of drivers Tprs .
