1 Pound Belfast Banking Company

The Belfast Banking Company Limited was absorbed into the Provincial Bank of Ireland in 1923, ending an independent issuing history that stretched back to 1827. Notes from the 1905–1909 series therefore represent the institution's mature period — commercially confident, well-established in Ulster, but less than two decades from extinction as a standalone bank.

Charles Skipper & East produced a substantial volume of Irish provincial bank printing during this period, and their guilloche work was among the more technically refined available to smaller issuers at the time. The London origin of the printing is worth noting — Irish banks routinely sourced their security printing from English firms rather than domestic ones.
