I have this book at home and will check it tonight.
For some details on the Master (in Turkish, but understandable with a web translator), see

Accordin to Tony Wood files, a Lt Baak of 14./KG 2 (a Me 410 outfit used for Intruder/nuisance bombing of UK) claimed a "two-engine aircraft" at 0351 hrs (German time) on 4 September 1943 at 200 m south of Lincoln. This is coherent with the location of Cranwell and the story as told by the Turkish site that the Master was shot down shortly after taking off.
