Dornier Do 17 & 215 Nightfighters (Kauz I-III) – List & seeking infos

[Huskie]

Hello,
I am seeking all additional information regarding these particular rare aircraft, especially with respect to WkNr., Stammkennzeichen, units & losses in order to complete this „Kauz puzzle“.

Unfortunately I haven't got any access to the GQM losses list (Freiburg is too far away).
Having studied several other open ressources incl. books and the web some information seem to be incorrect/unprecise.
Example: there was only one Do 17 Z-7 (Kauz I) !? --- There are photos showing at least 5 aircraft with individual codes (R4+HK, A, C, F & R4+EB).

In addition to that, there are pictures of one Do 17 Z-2 with glas nose & central 20mm MG FF, painted black overall,
having the „Englandblitz“ nightfighter crest, two lateral MGs in the B-Stand and the unit code R4+ZK (so 2./NJG 2)

Attached you an can find a list of my collected data so far (An ENGLISH translation can be provided if needed.)
Below a list Do 215 Werknummern, units etc.

Who has / knows where to find more ?

Huskie.
