Bradbury Wilkinson produced this note at their New Malden works during a decade when Portugal's Estado Novo government kept monetary policy extraordinarily tight — the escudo remained one of Europe's more stable currencies through the early postwar years, partly because Salazar's wartime neutrality had allowed Portugal to accumulate substantial gold and dollar reserves. That stability meant these notes circulated hard and long before replacement.
The sixth printing designation within P#159's type classification reflects incremental security updates rather than a redesign — changes detectable only through close comparison of watermark depth and plate registration between print runs.
