Hello Peter,
most probably you mean the summarised loss-lists?
These are stored in BA-MA RL 2 III 813ff.
There are files for personnel losses in 813 to 842 and files for material (plane) losses in 843 to 872. The files are sorted by units, e.g.:
821: personnel losses of Störkampfgruppen
844: material losses of Nahaufklärungsgruppen 1 to 102
858: material losses of Nachtschlachtgruppen 1 to 20
You can find the signatures of the material losses here:

The lists rarely mention the plane type and look like this:
27 January 1943: one plane missing during combat mission, reported on 31 January 1943.
The according personnel loss list would be:
27 January 1943: two missing during combat mission...
Hope that helps.
Best regards,
Christian
