Can I suggest that in addition to posting your query here, you also post it on Forum of the Mosquito Page website at:
Phorum :: WWW.MOSSIE.ORG Discussion Forum
Contributors to that Forum are immensely helpful, incredibly knowledgeable about the Mosquito and may well have details of the Squadron operations book or of specific missions. It really is THE place to find out about Mosquitos and their crews. If you can give any information at all - his name, his Squadron, station names - it will help and could be the key to a whole raft of information.
Try it, and good luck!
