I've extracted the service career of A/Sqn Ldr Ritchie from the LG, but can anyone fill in details about the units with which he flew. I believe he was with 1403 Met Flight in April 1941 and may subsequently have moved to 1405 Met Flight. His DFC was recorded in the LG on 18 May 1943 whilst with 143 Sqn.

I also have his CWGC certificate.
