William Green again has the type divided into three unofficial subgroups, A, B. and C - the differences again being the radar installation. However, one of his comments is obscure...
...and in context it's not clear if he's referring to the G-7c's...or the G-7 overall...and the -7c having FuG 240 Berlin N-1a. Only ten of the last mentioned subtype were completed...
On the issue of the G-6 variants, I've looked back at what he says about the G-6 engine installtion...and THIS is a enlightening;
So the Ju 88G-6 had BMW 810Gs installed while it was being built in parallel with the G-4 - and this is the mark distinguishing feature? The syntax of this would indicate that when the G-6 was the sole G-model in production after G-4 construction finished...the Jumo 213 was fitted."This variant (G-1), like the G-4 which followed it on the assembly line, was powered by BMW 810D engines of 1700 hp, the latter model only differeing in that it standardised on avionics introduced progressively by the G-1. Some G-4s were fitted with a schrage Musik installation of two upward-firing 20mm cannon, a similar installation being provided in the Ju 88G-6a manufactured in parallel and differing only in having BMW 801G engines."
This is strange - because fitting the 213E means the G-6 production line was in competition for engines with the Ju 188, Ju 388, the Fw 190D Dora and the Ta 152H. The 810G - which was a version of the E with different prop gearing for bomber use - must have been unsuitable.
