I'll get to work on untying the knot. The flyer describes the design of the Brossel cab:
Sheet steel
sleeper-cab on a steel frame (picture six), but there also were short-versions under "Brossel"-branding (see above).
"Motor Panel" also used sheet steel for their short-cabins (picture one),
sleeper-cabs were converted by Bankfiel (picture two).
But unlike brossel, there were also plastic cabins (picture three), but I have no information who built it.
To top it all off, there was also the short-door version of the LAD-Cab (picture four), LAD means Leyland, Albion, Dodge.
Here the "Motor Panels" range from 1958 in full beauty (picture five).
Is the confusion big enough now? But confusion is nothing unusual at Leyland. In Germany, "British Leyland" was called
"British Elend", Elend = misery. Or do we still want to talk about the different versions of Leyland, Albion and Dodge? How about the License- and CAD-Versions in Turkey, Israel or India?
