no data for WNr.2693, obviously an error because 2693 should have been a D1! I guess this is the one you're looking for

WNr.4861 E4 5./JG2 Uffz. Alois Dollinger (KIA), combat with Spitfire in the area of Portland  crashed, parashuted, near Sprakefield  100%
I Hope this helps you.
BTW, from which source is your (crash?) location data?
best regards,
Tomislav
