He 111 A3+BD is interesting because every other
A3+_D aircraft I know of was a Ju 188 or (in one possible case) a Ju 88. KG 200 used a weird coding system but +_D seems to have denoted the 4. Staffel and its detached Kommandos.
The Geschwader seems to have used He 111s in the East under (from memory) the
2. Staffel.
Thanks for bringing the photo to light.
