Hi John,
after your "exact wording" - taken out from the Lukesch material and which may circle around here and there - I am quite sure, that these are only fragments. In Rehms material are much more details than what you quote from the Lukesch source.
Rehms memoirs have the title:
"Kampfgeschwader 76 (KG 76)"
and the subtitle, concerning the Ar 234 story:
"13th Chapter of a Sqadron Chronicle"
and
not:
KTB Einsatzstaffel III./KG 76.
I bet, the material in front of you hasn't 52 pages describing the KG 76/
Ar 234 story, splitted into 27 subchapters.
All the best, Horst
