5 Dollars Colonial Bank

The Colonial Bank was a British-chartered institution operating across the West Indies and British Guiana, ultimately absorbed into Barclays Bank (Dominion, Colonial and Overseas) in 1926. By 1917, wartime pressures on shipping and banking supply chains made note replenishment from London a logistical problem, which likely accounts for the relatively small surviving populations of this issue across all denominations.

Perkins, Bacon & Petch had held the Colonial Bank contract for decades by this point, using their established intaglio methods. The S115 designation places it firmly in the specialist rather than central-bank series — issued by a commercial chartered bank, not a colonial government authority.
