20 Dollars Barclay's Bank

Barclays Bank (Dominion, Colonial and Overseas) was itself only a few years old when this note was issued — the DCO entity was formed in 1925 through the merger of three colonial banks including the Colonial Bank and the National Bank of South Africa. The $20 denomination suggests Caribbean issuance, most likely the British West Indies, where Barclays DCO inherited a substantial branch network. Bradbury, Wilkinson printed extensively for colonial commercial banks throughout the interwar period, their New Malden works supplying paper currency to institutions that lacked any central bank backing whatsoever.

Pick S101A places this in the private commercial issues, not sovereign note production — legally a bank obligation, not a government one.
