I remember us sitting at small tables along the other wall, Richard - each table at right angles to the window. (Could be wrong - I was only about 9!)
As to the "opening" of the M6, some confusion has crept in, because of two openings and two attempts to feature Bonds. Doug Ferreira did indeed arrange for Bonds - Minicars Mk E at that time - to be the first public cars on the motorway, when the Preston By-pass opened in
1958. I can't find them right now, but I have seen pictures of two of them, and the Wikipedia entry on Bond Minicar tells the story:
In a publicity stunt for Sharp's, three Bond Minicar Mark E's, two Saloons and a Tourer were the first cars to drive along Britain's first Motorway, the Preston By-pass when it opened in December 1958. The plan was for the second and third cars (driven by Alan Pounder and Doug Ferriera) to 'deliberately' slow down the traffic whilst the lead car, driven by John Woods the Production Manager and fitted with one of the new Villiers 247 cc engines, would shoot off into the lead and be photographed by the BBC. Unfortunately, the plan back-fired because the Bond beat the camera crew to the bridge where the shot was to take place! Consequently, the evening news only showed the second and third Bonds amongst the traffic on the opening day. Now part of the M6, this event was recreated for the motorways 50th anniversary by the BBC's Inside Out programme in 2008
Churchill died on 24 January
1965, so the use of Equipes was perhaps for the opening of a later section of Motorway - perhaps Preston to Stafford, in 1965?
