Paul is correct. The RAF Museum London 2007 list of Flying Logbooks was made available by a member here several years ago and I kept a copy.
The List includes one entry for S/Ldr CF Ambrose:
"Accession no MF10018/1
Title: Pilot's flying log book of Sqdn Ldr C.F. Ambrose, 1940-1946
Maker: Charles Ambrose
Prodn date: 28 May 1940-31 December 1946."
Although the Museum has re-opened for booked visits, the Research Dept "remote enquiry" service (ie email, presumably) is suspended until 1 April 2024.
However, their page says it rather differently...
In earlier years I've found their response and charges for paper copies of Flying Log Books both timely and reasonably priced.
Perhaps by now digital copies might be possible - save them a lot of labour.
The pdf list is from 2007: may have been updated in the years since.
Happy to email a copy if of use to you.
