Thank you Wayne Little!
I'm looking into the aircraft flown by Ofw. Paul Gildner of 4./NJG.1 in febr/march '41
A 'dedicated' request summarizing the situation and the kind of data I'm looking for can be found
HERE (and also on various other forums)
Sofar I've found out some details about his plane with the help of people on forums such as these. Most likely it's an all black (early Luftwaffe night fighter scheme) BF-110D or just maybe an early 'E' type. The long tail with dinghy in the back is apparently visible on a picture of a BF-110 with the right fuselage code taken some six month later. Still hoping to find further details about this aircraft though.
However should no further information be available on his plane I might have to take a step back if you will and try to make an educated guess (by asking maybe some more general questions such as these) as to the specific features that
might have been present at the time.
Speaking of which, is there per chance any visual difference between daytime victories and nighttime victories as far as these kill markings go on a typical early all black nightfighter (it seems rather useless to me to put a black victory marking on a black A/C if you know what I mean)
I have the excellent Eduard 1/48 kit in mind (still need to decide upon which sub-type though, hopefully based on further technical details on his plane) and I've also tracked down two decal-sets which can be used to piece together the right fuselage code (G9+HM) in the right scale and colour.
