Found them in the Excel-File ...
given loss location: Rennes (F); 3.(F)/123 (or 3.(F)/A.Gr. 123)
unfortunately no more plane details (just "Ju 88" is given).
Crew:
(F) St.Fw. Garschhammer, Heinrich (unharmed)
(B) Ofw. Kreuzer, Michael (unharmed)
(Bf) Ofw. Kirch, Siegfried KIA
(Bs) Uffz. Harnisch, Heinz KIA
This info mostly comes from the
www.absa39-45.asso.fr website.
Please note the different spelling of the radio-op's name (Kirch - not Kirsch), which is in accordance with the VDK database.
Hope, this helps a bit ...
Regards from Karlsruhe/D,
