Was operating both 40 mm systems a serious logistics problem?

When did the Royal Navy recognize that supporting both the two-pounder Pom-Pom and 40 mm Bofors created a logistics problem?

It was an inconvenience, but not a decisive wartime problem; immediate demand for weapons outweighed the benefits of strict standardization.

Peacetime efficiency mattered less than mass-war necessity. Supplying two systems was inconvenient, but a navy mobilizing ships in great numbers needed every effective weapon it could obtain immediately. The practical response was to manage the extra burden rather than wait for complete standardization.
