HRH Prince Philip

Prince Philip visited Park Royal in 1959 or 1960?  It has to be no earlier than 1959 as Sir Wavell Wakefield took up his position as Chairman that year and if it were later than 1961 then Leyland would be represented, and it is not; though Bill Black became Leyland's chairman in 1963.
Does anyone know the exact date of Prince Philip's visit?

Prince Philip subsequently visited the Leyland factory in 1966 (four years after Leyland's acquisition of ACV and thus PRV also) and drove an Atlantean around the test track with passengers Don Stokes (MD) and Sir Bill Black, Leyland's soon-to-retire Chairman and former Chairman of PRV (and ACV's MD) whom he met on his PRV visit below.

Here begins Prince Philip's tour outside PRV's offices in Abbey Road, Park Royal.  His Rolls Royce having been swiftly replaced for the 'photo-op' by RM2, the second prototype Routemaster.  All designed to maximise the publicity in the Royal press that PRV is where the Routemaster is built.

Who is the guy in the Top Hat - I could hasten a guess that he was Tommy Harwood, always game for a laugh and a founding member of the Park Royal Concert Party; he would do that!.
