Use of 4-bladed propellors on the Ju88?

[ArtieBob]

IIRC, KG 30 was formed in September 1939. At that time many of the Ju 88s were from the Dessau built Nullserie and Stammwerkeserie. The documentation is pretty sketchy, but I have a number of photos showing bombers, Aufklarers and even some early "C" types with 4 bladed props. It is almost certain that the Nullserie had 4 bladed props and probably the Stammwerkeserie and possibly even the early Bernburg Grossserien. So, for dates from the inception of KG 30 to the first half of 1940, I would guess is the window 4 bladed Ju 88s might have been in service with KG 30. BTW, as V-E day approached, the first of the 4 bladed Ju 88 G-7s were reaching final assembly. AFAIK, none reached operational service, but in one photo it appears the visible prop blades are at 90 degree angles (or is it just a vivid imagination)?
