Hi...
If you follow this link
www.aircrewremembrancesociety.com/luft1944/Detering.html, you will get a lot of information on this machine, one of two listed for that night, the other apparently being 4D+OL.
There is a photograph of a Ju88 with Meänderung (wave pattern/meander) camouflage and a
small '4D' Geschwader code. The remainder of the code, if this is your machine, may well have had standard size letters. At this time of the war, the Geschwader codes were often reduced to one-fifth of standard size.
There is also information on the crew members, and an account of the events of that night. Hope this is of use to you.
Regards...
Paul
