'Gifted' Lancaster
The definitive reference work on gifted aircraft in the RAF is an Air Britain publication called 'Gifts of War' by Ray Sturtivant. It is largely about Spitfires because they were, by a long way, the most numerous gifted aircraft in WW2 but the book does include other types.
I have a copy and would look this up for you but I'm away from home until the 17th of this month. I'll have a look when I'm back and let you know what I find.
Good luck with the search.
