Since the C and D series were build at the same time let us have a look at the cockpit of the D-series.
My sources for today:
"Report-No. 260-28 Analysis of the Messerschmitt Me-110 Airplane" from Vultee Aircraft Inc.
"Life" Magazine from 21. April 1941 Page 34/35
"Messerschmitt Bf 110 C, D and E" from John Vasco and Fernando Estanislau
"Beschreibung und Einbau der Zusatzanlagen für das Flugzeugmuster Bf 110 D L.Dv.T2413/1(Entwurf) / (Nachtrag 1)" from November 1940
The first 3 pictures are from the Bf-110 D-0/B W.Nr.3341 S9+CK build in Juli 1940 and shot down on 15. August 1940.
Just look at the Revi holder with the "Schwenkplatte SP 1A" for the Revi C12/D which should also be in every C-7.

The only 39 new build C-7 were produced from Juli 1940 to September 1940 (see "Messerschmitt Bf 110, Me 210, Me 410" from Heinz Mankau/Peter Petrick)
So we have a good look at the same equipment in the instrument panel.
Here is a drawing out of the manual which shows the instrument panel of a C-series with the additional 2 lamps for the D-Series.

In my next post I will show what we have in "Cliffs of Dover" as a cockpit for the C-7.
