Asfordby Storage used to be well known to enthusiasts for some of the older motors they ran: there was an Atkinson Borderer, GJF 740N, which lived to a ripe old age and has been restored quite recently, and they also had the one-off View-Line rigid 6-legger, which had been built new for the RTITB at High Ercall. t became a curtain-sider with Asfordby, improving its proportions no end.
I also have a recollection that they used a Scammell Highwayman for shunting empty rail wagons at, perhaps, the Pedigree Pet Foods site: was that rail-linked? Not as far fetched as it sounds: when Bowker opened its rail terminal at Bamber Bridge, we bought a new Ford ‘County’ 4x4 tractor for moving rail wagons. As I recall, the 4 cylinder versions was rated to move 400 tons (slowly!) and the 6 cylinder could shift 600 tons. I do have a photo somewhere
