Hi Steve,
I have a book by Wing Commander (I think) Bruce Robinson called "LANCASTER - The Story of a Famous Bomber"
Signed by himself & crew. It is No. 311 of ?
It is mainly about the craft rather than the people, but has many photos, plus a whole list of all Lancasters & Manchesters by serial No. & their fate. This is where I got the flight hours of JA969 from. Give me a while & I will go through it to see if I can find any info in it regarding JA969 or people in your photo.
I lent it to a friend a while ago, who's father was in Lancasters. His dad found a photo of himself & crew. He was over the moon, but died shortly after.
I am not an aviation "buff" but have the book passed on by my late father. It is worth so much to me for this reason.
Geoff
