Thought that forumites might be interested in these pictures.
They show my great uncle, William (Bill) George Baker and his wife who owned the Clarendon Bakery at 1 Clarendon Street along with their delivery 'boy' with their Reliant van.
Not sure when these were taken but late 50's or early 60's is likely. That model of Reliant was made between 1935 and 1950 and this one looks well used.
