This is one of the cars that took part in the Lancashire Automobile Club's Manchester to Blackpool Veteran and Vintage Car Run in June 1975 and is pictured just after the start at the junction of Peter Street and Lower Mosley Street.
It's the 1924 Bentley 3 litre of Mr D.C.Y. Dickson and the programme of the event had this note about the car:
58. Mr D.C.Y. Dickson, Garstang, Lancs.
1924 Bentley 3 litre Blue label tourer 15.9 h.p. 4 cylinder.
Jointly owned by Mr. Dickson and his brother Mr. J.C. Dickson (No. 57) this car has been driven alternately by them in every run except last year when it obligingly stood down for a Rolls-Royce! Twice winner of the Daily Telegraph Challenge Trophy; three times winner of the Vauxhall Trophy it has also won the Turner Trophy.
(Note: the Daily Telegraph Challenge Trophy was awarded for the best performance by any competitor, the Vauxhall Trophy went to the best performance by 'Cars of 1919-1924 up to 3,000 cc', and the Turner Trophy was awarded for the best performance in a special test.)
