Various.

Of the five companies, three are subsidiaries of the depositing company. City and West End Properties Limited, property company, was established in 1897 and based at 101 Leadenhall Street. In 1907 it moved to Bush Lane House where it remained until it was acquired by Trafalgar House Development Limited in 1964.

Corbett and Newson Limited, property company, was acquired by Trafalgar House Development Limited in 1966.

Woodgate Investment Trust Limited, property company, was incorporated in 1932 and shared offices with Corbett and Newson Limited at 17 Gracechurch Street (to 1933) and 34 Great St Helen's (1934-66). It too was acquired by Trafalgar House Development Limited in 1966.

Two of the five companies have no connection with the depositing company. Metropolitan Properties Company Limited and Consolidated London Properties Limited (which was acquired by Capital and Counties Properties Limited in 1964). The inclusion of these two companies derives from their previous association with City and West End Properties Limited, with which they shared both offices and directors before 1964: in some cases their records are intermingled.
