There is a new series on RAF bomber losses in the Med, but ,so far, it's only up to end of 1942.
" RAF Bomber Losses in the MIddle East and Mediterranean" --David Gunby and Pelham Temple.
There's a book on RAF operations against Ploesti that has good detail on some of the RAF bomber losses. Its called "Through Darkness to Light" by Patrick MacDonald. Undoubtedly some of these losses were to NJG-101.
Also, post on the RAF Forum, there's a wealth of information there.
