1 Pound Royal Bank of Scotland

The Royal Bank of Scotland's interwar pound series occupies an interesting position in Scottish note history — these were issued during a period when Scottish banks still operated with near-complete autonomy over their own paper currency, a privilege that survived every parliamentary attempt to curtail it. W. & A. K. Johnston, the Edinburgh cartographic and security printing firm, handled production throughout the run, with G. W. Bacon brought in as a partner arrangement that reflected a broader consolidation in British specialty printing during the late 1920s.

The 1929 financial crisis had little visible effect on the series itself, which continued uninterrupted — Scottish clearing bank notes were never subject to the emergency restrictions applied to Bank of England issues during the same period.
