The Dexter bow-front is brown - I think the image has been distorted a bit. that picture appeared in Alan Thomas’s ‘Trucks’ book back in the early eighties.
All the colour pictures I’ve seen of Dexters were brown with red chassis/wheels. Other fruit hauliers of the era were Foleys, McCanns, Smithards and Fieldings.
I’m surprised there haven’t been any pictures of Harpers, George Davies, Michael McKennas, Kirkdale Haulage, Jarvis Robinsons Transport, etc appearing on here - but then again, not many people would stand at the roadside in Liverpool to take pictures back in the day - suspicious minds 'n all that. The only one who took them in Liverpool and who gets regular publicity is Peter Davies and all his have a copyright - another reason they’re not on here.
