20 Pounds Clydesdale Bank

Clydesdale Bank's £20 from this period sits in an interesting transitional stretch for Scottish commercial banking. The signature block tracks a single individual — Alan Cole Hamilton — across two different job titles, reflecting structural changes within the bank rather than any change in issuing authority. His promotion from Chief General Manager to Chief Executive mid-series is one of the more legible pieces of institutional history you can read directly off the note itself.

The 1987 and 1990 dates fall within Clydesdale's period of full ownership by Midland Bank, which had acquired it from the Midland's own parent restructuring. Scottish banknote-issuing rights remained intact throughout — a function of separate Scottish banking legislation, not corporate negotiation.
