5 Rials

Bradbury Wilkinson's contract with Oman in the mid-1970s came during a period of rapid institutional consolidation — the Central Bank itself had only been established in 1974, replacing the Currency Board that had managed the rial saidi since 1972. This note belongs to the first full Central Bank series, issued while oil revenues were reshaping the country's financial architecture faster than its bureaucratic structures could comfortably absorb.

Bradbury Wilkinson closed in 1990 when De La Rue acquired the firm, making any note from their Oman contracts a fixed point in that printer's history.
