1 Pound National Bank of Scotland Limited

The National Bank of Scotland Limited was formed in 1825 and became one of the more cautious issuers among the Scottish chartered banks — slow to reduce denominations below £1 even as English practice pushed toward smaller notes. By 1880 the bank was well into its mature phase, with a branch network spanning central and southern Scotland.

Perkins, Bacon & Co. supplied engraved plates to Scottish issuers across decades, their steel-engraving method favored precisely because it resisted forgery better than the lithographic alternatives common on the continent. The firm's London origin is sometimes mistaken for the place of issue — the notes circulated exclusively in Scotland.
