5 Kroner - Haakon VII Government in exile, war notes

Norges Bank's London-issue notes were produced under the authority of the Norwegian government-in-exile following the German occupation of Norway in April 1940. The occupying administration had immediately seized control of Norges Bank's Oslo operations, compelling the government to establish parallel currency issuance from Britain to fund Norwegian forces and resistance activities. Waterlow & Sons handled several such exile-government contracts during the war years.

The "B" suffix in the Pick classification distinguishes this from the earlier P#19A, reflecting a printing variation within the same wartime London series.
