F/O Leslie Valentine CdeG RAF
My father Geoff Norton DFC CdeG (still alive) was good friends with your father in 88sqn. Apparently toward the end of the war because they both had excellent navigators they would take it in turns to lead the squadron on raids.
If you look at Page 2 of Boston Questions in this section you will see a photo and an article of a raid made by 88 sqn led by my father.
Strangely enough my father was born in Banbury, shame they never managed to meet up before your father died.
