Duncan, I have no desire to start an argument. LOL However:-

Laurie’s “B4” was always painted a metallic dark maroon colour, i.e. in accordance with the house colours of his carrying business, as were his Bedford trucks, Morris Minor convertible, V8 Special and DeSoto? sedan.

Years ago I heard a rumour which I have just now had confirmed, that the car was turned into a hot rod and this tied in with the modified car I came across, and that later it was broken up for parts. Please send me a PM, whereupon we may be able to arrange a phone conversation.
