5 Pounds North of Scotland Bank

The North of Scotland Bank Limited, headquartered in Aberdeen, was one of the smaller Scottish chartered banks that survived into the twentieth century largely through regional loyalty rather than scale. By the late 1920s it was already operating under pressure from the larger Edinburgh and Glasgow institutions, and it would ultimately be absorbed by Clydesdale Bank in 1950.

Bradbury Wilkinson's involvement is worth noting — the New Malden firm handled security printing for dozens of colonial and provincial issuers during this period, and their intaglio work on Scottish provincial notes tends to be technically superior to the notes' relative obscurity might suggest. The P#S640 series spans six years, and dating individual examples precisely requires examining the manuscript signatures, as the printed date range covers multiple cashier appointments.
