Hi Peter,
if you look on this film strip of guncamera on footnote.com, there looks like from 78th FG (you propably have book "Orli Duxfordu" by Garry L. Fry - for other, this is czech version of book The 78th Fighter Group in World War II - ISBN O-9625860-2-1 from Phalanx Publishing ) - look on the page 122 in czech version of this book.
30th March 1944- one flight from 82nd FS strafed boots on the Rhein river - this is propably this shoot :

30th March 1944 - one flight shoted down Do 217 over Twenthe/Enschede airfield ....I think, this is this "Do 217" - but this is only my speculation (look at the page 112 of czech version) - propably wrong determineted type of aircraft by US pilots .
In Alliend and Soviet Air force is topic
US fighter´s victories over Bf 110/Do 217 between January and April 1944 and maybe some who is interesting in US fighter help us.
