Back in the late 1960s Mixconcrete was one of AEC’s biggest customers. At this point it already had 150 of them on its 400-strong fleet, but was keen to purchase another 250 over the next few years. Whether it did or not, I have no idea.
This Marshall 6x4 was one of 12 similar trucks delivered in August 1969. For those of you who are interested in the technical spec, it had a 20-ton GVW and was powered by the AV505 engine, developing 151hp at 2,400rpm. It had a six-speed constant mesh transmission and two single-reduction 7.14:1 ration driving axles.
