Thanks for the advice Bookbox, much appreciated.
I have now found further information by looking on the 1939 Register; which showed that he was based at Holloway Fire Station.
Holloway Fire Station: The station at 84 Mayton Street, N7, was built in 1908 to replace an earlier 1871 building. During WWII, it was a vital part of London's fire defence.
AFS Mobilisation: When the AFS was formed in 1938 to bolster regular firefighting resources for wartime, Holloway Fire Station became a central hub for the area, supporting six sub-stations, including one at Shelborne Road School.
Nationalisation: In 1941, during the height of the Blitz, the AFS and local brigades like Holloway were merged into the National Fire Service (NFS) to create a more unified response to aerial attacks.
Post-War and Closure: The station returned to the control of the London Fire Brigade (LFB) in 1948 and continued operations until 1975, when it was replaced by a new station on Hornsey Road.
I’ve also found some photos of Holloway Fire Station online.
