5 Pounds Northern Banking Company

The Northern Banking Company Limited was one of the older Belfast-based provincial banks still issuing its own notes into the early twentieth century, a privilege that would effectively end when the Irish Free State and Northern Ireland partition arrangements reshaped the note-issuing framework after 1921. The 1918 date places this note squarely in the wartime period, when paper quality and ink supplies across British commercial printers were noticeably constrained — Perkins, Bacon were still producing security work, but the material limitations of 1917–1918 are occasionally visible in surviving examples of this series.

Perkins, Bacon's involvement gives it reliable intaglio security printing credentials, the same firm responsible for early British colonial stamp and banknote production across several continents.
