That's handy John, thanks.
It says:
Formed 3.43 in Deblin-Irena from the Ergänzungs-Zerstörergruppe with:Stab/Erg.Schlachtgruppe from Stab/Erg.Zerst.Gr. (Bf 109, Fi 156)
1./Erg.Schlachtgruppe from 3./Erg.Zerst.Gr. (Bf 110)
2./Erg.Schlachtgruppe from 2./Erg.Zerst.Gr. (Hs 123, Hs 129)
3./Erg.Schlachtgruppe from 1./Erg.Zerst.Gr. (Bf 109, Fw 190)
So I'm assuming I'm looking at photos of 1./Erg.Schlachtgruppe. However, since the Erg.Zerst.Gr. was also formed in Deblin-Irena:
Reformed 18.4.41 in Deblin-Irena with: Stab/Erg.Zerst.Gr. new
1./Erg.Zerst.Gr. from Erg.Staffel/ZG1
2./Erg.Zerst.Gr. new
3./Erg.Zerst.Gr. from 5./EJGr.Ost
I need to know the date so I can tell whether the unit was 1./Erg.Zerst.Gr or 1./Erg. Schlachtgruppe at the time of the photo
Thanks
