20 Pounds Royal Bank of Scotland

Bradbury Wilkinson handled the Royal Bank of Scotland's higher-denomination issues through much of the postwar period, printing from their New Malden works in Surrey — a facility that also produced stamps and bonds for dozens of governments worldwide. By 1969, the Scottish banks were still operating under a system of note issue that predated the Bank Charter Act of 1844, which had never applied north of the border in the same way, leaving institutions like RBS with retained rights that English banks had lost over a century earlier.

The watermark remains the primary security feature — relatively modest by later standards, but consistent with Bradbury Wilkinson's production norms for this period.
