That is indeed the case. Some county Borough remained united with
their "parent" county for police purposes (other did not) but in the

the Met.

There were originally a lot more non-county borough police forces, but
the government forced mergers, particularly after the war. By 1960 it
was nearly only county borough forces which retained their
independence. Only the independent Birmingham, Hull, Leeds, Liverpool-
Bootle, Manchester-Salford, and Dudley-Walsall-Warley-West Bromwich-
Wolverhampton forces remained in 1974.

I think that the only other County Borough within present day London was
Croydon. Anyone know better?

This is correct. Of course, most of Middlesex's municipal boroughs
had met the population criteria to be made a county borough, and their
efforts to do so had been opposed bitterly by the Middlesex County
Council.
