There was a picture posted on here quite a while ago of a trailer belonging to a scottish m/e haulier. Cant for the life of me remember the name but the trailer was quite distinctive, white sign written tilt with quite a few names on it IIRC,and a very vivid green paint job on the trailer body and instead of a single belly tank it had extra fuel tanks under the outer sill of the trailer. i remeber seeing it in Dover in the 8o`s.
Appartently the guy used to do North Africa as well as M/E.
Some of the old M/E hands from on here recognised and identified it…im sure that if one of our resident picture wizards or 80`s archivists reads this then it may jog a memory or to and they can point you in the right direction.
Sorry i cant be of more help but im sure someone else will.
