Lockheed Constellation

Might be a L-049 or L-749A. Note that, except G-ANUR sold in July 1962, all the B.O.A.C's Constellations were removed from the park during the period 1955/1958.

Lockheed Constellation of B.O.A.C-British Overseas Airways Corporation.

'M' letter on the front landing gear. Two aircrafts could match:
G-AHEM a L-049 used by B.O.A.C from 1952 to 1954.
G-ALAM a L-749A which entered service with B.O.A.C in June 1948, and crashed in March 1954 at Singapore.
Therefore, it must be a pre-1954 archive. Another aircraft of the type in the background.
