Still no sign of RN Searle anywhere.... I'm puzzled that no reference found in Flight as that details promotions, so would have expected to find him as P/O and if any higher... no such luck. No response to request on Coastal, but always hopeful!!
Are the ORB's in electronic format? There are regular requests for ORBs for various units so if you feel like making them available for others to research, let me know....
