This eight wheel tanker truck, built with the Liverpool-made prefabricated Multikit cab, and two other models are the subject of Modelplan 232 by Alex Barker, available from MW Mail Order. They have been built by the Meccano Society of Scotland modeller Dave Stanford and feature in some of his photos from a meeting of the society in early 2020.
The examples in MP 232 use a worm and pinion steering set-up, which works, but has no ‘feel’ to it. Dave Stanford’s examples use a long rod to the rear and use a contrate and pinion steering mechanism. This works well and so my own examples have been built using this method.
