5 Rupees Central Bank of Ceylon

Bradbury Wilkinson printed Ceylon's banknotes for decades, and this series continued that relationship through a politically turbulent stretch — Ceylon became the Republic of Sri Lanka in 1972, yet the Central Bank continued issuing notes under the Ceylon name until the transition to Sri Lanka branding was completed. Notes from this series dated after May 1972 represent that awkward institutional overlap, where the state had changed its name but the paper in circulation had not.

P#73A spans a wide date range, so the specific year of issue matters considerably to completeness collectors.
