5 Dollars Colonial Bank

The Colonial Bank was a British overseas institution chartered in 1836 to serve the Caribbean, operating branches across Barbados, Trinidad, British Guiana, and several smaller islands. By 1903 it was already in the late stages of independent existence — Barclays would absorb it in 1925 alongside the Anglo-Egyptian Bank and the National Bank of South Africa to form Barclays Bank (Dominion, Colonial and Overseas).

The S suffix in the Pick reference denotes a specimen, which tracks with Perkins, Bacon practice of retaining archive examples from colonial and commercial bank printings. Perkins, Bacon held the intaglio plate work for dozens of such institutions simultaneously, and specimen retention was routine.
