10 Pounds Ulster Bank

Ulster Bank's pre-decimal £10 notes from this period occupy an unusual corner of Northern Irish banking history. Unlike the major London clearing banks, Ulster Bank retained its right to issue its own notes under the Currency Act arrangements applying to Northern Ireland — a privilege that persisted long after similar rights had been extinguished elsewhere in the UK.

Charles Skipper & East were the workhorses of commercial bank note printing in Ireland and Britain for decades, handling security printing for numerous provincial issuers. The "Northern Ireland" printer attribution on P#317 should be treated with caution — Skipper & East's principal facilities were in London, and regional attributions in catalog records for this series have a history of reflecting the client's address rather than the actual press location.

The nine-year date span suggests wartime and postwar production runs overlapped without significant design revision.
