10 Pounds Belfast Banking Company

The Belfast Banking Company Limited was absorbed into the Midland Bank group in 1917, yet continued issuing notes under its own name right through the mid-1960s — a commercial arrangement that left the issuing identity intact while the actual banking operations were folded into a much larger British clearing bank. This disconnect between nominal issuer and operational reality is precisely why the series ran so long without meaningful design revision.

Northern Ireland's unique constitutional position allowed a handful of commercial banks to retain note-issuing rights long after such privileges had been extinguished elsewhere in the UK, and the Belfast Banking Company was among the last to exercise them before the Midland finally wound up the brand entirely in 1970.
