hi,indeed he claimed a DO217;Cynrik De Decker who is an expert on aviation told me that he toke the plane for a DO217 as it has a twin-tail just like the BF 110.It seems that the only DO217 that was shot on 19/4/44 crashed in the Northsee. There is an German report(Deutshe nachtjagd -materialverluste) telling;Capellen 8km N of Tienen,19/4/44 by UBERFUHRUNGSFLUGT with BF110 G9 HZ Wnr 740148 Uffz A Wachtel was killed. The only discussion is the date because 5 eyewithnesses are telling me ;it was in the summer 44 at least july:august
thanks André
