During a brief trip to my hometown last week I finally managed a visit to the British Commercial Vehicle museum. (I have an excuse. I left 23 years ago and the museum is only 20 years old).

To the casual car enthusiast this eclectic collection might only be of passing interest.

But if you’re the sort of person who appreciates raw engineering, has a grasp of the main phases of C20th century history and an eye for styling and graphics, this place is well worth a couple of hours of your life.

It neatly spans – through road vehicles and a few buses – the development of the commercial vehicle from the 1896 Thornycroft (front-drive and rear-steered) Steam van to the intriguing 1986 Leyland TX450 concept truck (a low-rise, aerodynamically styled machine with an extruded aluminium chassis).
