Scott did make some actions for C&H after WWII. At that time substantial trade work was also being done for C&H by J. Blanch, which also did trade work for Churchill et al.

C&H's extensive Gillingham Street Works in London burned down in 1922. Gunmaking continued at several locations after that (including Birmingham from 1933 to 1935), but WWII military contracts displaced the sporting gun manufacturing. And after the war, Coggies might have come from anywhere. But at least until 1922 and probably for some time after, Cogswell & Harrison was one of the very few gunmakers turning out truly London-made boxlocks.
