I think Peter Brown & Alan Wharrier worked for International Transport company ‘English Mustard’ who ran beige coloured Magirus-Deitz trucks to Europe in the 70’s & 80s.
They left there and setup Brown Wharrier, doing mostly European groupage work with Tilts, I remember they had a ‘V’ Reg Scanny 141, and a Ford Transcontinental, and in the later years leased a load of DAF 3300’s they were somehow also connected to ‘Taxi Freight’ another local transport company.
