Junkers Ju 88 P - Missions and Units?

[Harry64]

Hello,

maybe someone can help me with a few questions about the Ju 88 P, the units which used them and missions.

Ju 88 P1 - some 40 units built, - but which unit used them and where?

Ju 88 P2 - ? units built, - which unit used them? I´ve found this (Erprobungskommando 25) is this correct?

Ju 88 P3 - ? units built, - delivered at one Staffel of the Nachtschlachtgruppen 1, 2, 4, 8 and 9, is this correct?

Ju 88 P4 - ? units built, - which unit used them and where?

Also I have found in the book from Dierich "Die Verbände der Luftwaffe" that in 04/1943 the III./KG 1 should be converted to Ju 88 P and used in Fliegerdivision 1 and 2. But I think that can not be true, or?

Fine and grateful if some specialist can help me.

PS: can anyone recommend a book about the Ju 88 P?
