Warren Fisher signed British Treasury notes in his capacity as Permanent Secretary to the Treasury — a civil servant, not a banker, which reflects how these notes sat outside the Bank of England system entirely. The Treasury had taken over direct currency issue in 1914 as an emergency measure under the Currency and Bank Notes Act, and by 1919 the arrangement had long outlasted the war that justified it.

Fisher's signature appears on several series. The transition back to Bank of England issue didn't complete until 1928, when the Currency and Bank Notes Act finally wound down Treasury control. Pick 357 falls squarely in that interregnum period — neither wartime emergency nor peacetime normality.
