Hi,
The only mention of 149 Squadron during those dates is 28/29 November 1942, a raid on Turin. A Stirling was hit over Turin and again over France, crashed into the sea.  5 men bailed out but 3 were still in the plane.  Flight Sergeant RH Middleton awarded a posthumous Victoria Cross.
No mention of Flt Lt  Kellaway in the book.
16/11/1942:   raid on Genoa, 3 small German towns bombed.
19-20/6/1943:  raid on Le Creusot
Sorry......no much info there for you
