ICM,
yes he did well for a hostilities only non pilot. 4 Group had a reputation for promoting and appointing non pilots to such posts . I think an A/G called 'Lofty' Lowe became OC 77 at one time.
The last entry in the log book is Jan. 8th 1946 from Palam to Poona in 'Dak' KP 293 (difficult to read !) Co-Pilot. Interestingly once he became the squadron boss he does not bother with monthly summaries etc. No mention of any incidents.
