Peter, I have the same data as you but am inclined to think it was some type of clerical error. Note that I also have another incident for WNr.4081 while with IV./KG54 on 3-Jun-41, this time as a Ju88A-5. The incident was reported as a Fehlstart at Lechfeld with a 60% damage assessment.
Not quite sure I get what you're saying, but to me the first two incidents make sense. Surviving Ju88A-1s were in many cases upgraded to A-5s. The last report for the machine as a D-1 however seems of whack.
Thanks Peter & Jim.
Peter, the 1st example you give with a copy from the Loss Records the W/Nr is 4081 but the 2nd copy looks more like W/Nr 4091. If this is the case then to me there is no 3rd conflict.
one more general comment on a suggested conversion of a Ju88A-1 to Ju88D-1 Baureihe:
a Ju88D-1 (or Ju88D-5) recce aircraft would be based on a Ju88A-4 bomber type with many technical changes compared to a Ju88A-1 (wings, engines, fuselage etc.). For a Ju88A-1 type, a conversion to a Ju88A-5F or Ju88D-2 would be more likely.
