5 Dollars Barclay's Bank

Barclays DCO — the Dominion, Colonial and Overseas arm — operated as a quasi-central bank across much of British-administered Africa and the Caribbean during the 1940s, issuing notes that had full legal tender status in their respective territories despite originating from a commercial institution registered in London. The 1940 date places this note squarely in wartime production, when shipping disruptions and security concerns made the management of colonial currency supplies genuinely complicated.

The "S" suffix in the Pick reference denotes a specimen. Bradbury Wilkinson produced specimen notes with serial numbers cancelled or replaced by zeros and typically punched or perforated with the word SPECIMEN — standard practice for the firm when supplying reference examples to issuing authorities and correspondent banks.
