Bradbury Wilkinson printed the entire P#21 series from their New Malden facility, and the signature progression across the run reflects two genuine personnel changes at the Central Bank rather than reissues prompted by policy shifts. Duncan Ndegwa had served as the CBK's first governor; his replacement by Philip Ndegwa in 1982 midway through this series accounts for the overlap in signature combinations collectors encounter. Harry Mule's long tenure as chief cashier anchors most of the run.
The "Subiudyo" cashier signature appears only on the final date issues and is notably scarcer than the Mule combinations.
