Bf 110 cockpit, Wahlschalter and bomb load.

ok I agree

I found another 2 pics in "Kagero Monografie Vol.16". Not the best source since they took a pic of a C-series with FuG IIIa-U and declare it as FuG X.

By the first pic Kagero writes it's a Bf-110 C-2. Could be possible, but can't confirm it since I have no additional data. Interesting is the position of the clock and the AFN-1 ( field mod? )

By the second picture they write "assembly of pilot's cockpit equipment at plant in Augsburg". This indicates this cockpit as one of the D-Series, since Messerschmitt doesn't built any C-Series after the begin of the D-series.

The last C-2 in the Mtt-plant was build in January 1940 and D-Series production started in March 1940 to Sept. 1940.

Now let's see what the cockpit of the E-series is like.

Sources of today:
"D.(Luft)T.2110 C-2,C-4 bis C-7, D-0 bis D-4, E-1 bis E-4; Bf 110 Flugzeughandbuch Teil 9D; Bordfunkanlage" July 1942
"D.(Luft)T.2110 C, D und E; Bf 110 C, D und E Flugzeughandbuch Teil 8B; Einbau und Prüfung der Abwurfwaffe; Heft 1: Bf 110 E" May 1941
"Deutsche Flugzeug-Cockpits 1935-1945" from Kennrth A Merrick
"Ersatzteilliste Bf 110 C" January 1940 with updated pages (intruduction date see lower right corner of the page)

OK, let's begin with a nice cockpit drawing(first source) of an E-Series cockpit (see the heater knob top right).
Bf-110 E juli 42.jpg
This is the standard cockpit for the E-series. You can also see that instead of the electrical prop-gauges now the switches for the automated propeller pitch are installed. Good to see on the left side the fuse box with the switches for the fuel pumps.
Also some other instruments were moved.
This drawing can be taken for true, since a picture (2. source) clearly shows the switches in the same position.
Bf-110 E May 41.jpg

But now it gets tricky.
Two nice pictures of an E-1 W.Nr.4114, SJ+KB(production code), LN+FR(military code) of 1.(Z)/JG 77 build Aug.1941 and landed in Sweden on 1. Sep.1941.
Bf-110 E-1 august41.jpg

First some additional info.
The production of the E-1 ended in August '41 with W.Nr. 4116 and it was the last Bf 110 which the Messerschmitt plant in Augsburg produced(see "Messerschmitt Bf 110, Me 210, M410" from Mankau/Petrick page 324).
The last E-series A/C were build in Januar '42 and production of the F-Series started in Dec. '41.
As a side note the F- and G-Series were build at the Luther-Werke(formerly MIAG) and Gothaer Waggonfabrik which also produced the earlier Series.

My personal conclusion:
since they needed place for the outer temp. gauge (below the heater knob), they changed the position of the automatic-switches to the left, above the prop-pitch-lever.
To do so they used the spare parts for early C- and D-Series, wich were introduced to update the manual prop pitch to the automatic prop pitch system.
I can justify this conclusion, since there is no additional plate to cover the empty gauge hole to the right of the outer temp. gauge.

See spare parts for Bf 110 C (4. source).
First one is for normal C-Series with manual prop pitch. (see part-# 14)
Bf 110 C spare parts.jpg
Second one is for updated C-Series with automatic prop pitch. (see part-# 26(new box), 27(Cover plate), 28(prop-lever) and 29(switch))

look here what I've found. looks like a proper 110 C cockpit instrument set:

The lock switch for the artificial horizon is missing, but a good job from Eduard.

Let's have a look into the cockpit of the Bf 110 F-Series.

Left side:
Bf 110 f left.jpg

The housing for the prop pitch lever and switches is now standard. Above them the 4-switch-fuse-panel for the fuel pumps(since the belly tank[Dackelbauchtank] was deleted, the panel changed from 7 switches to 4).
There is an additional knob on the right throttle lever, to activate the landing light when pressed.

Front panel:
bf 110 f-2.jpg

For better instrument flight the panel was changed. Also the 2 control lamps, above the variometer(k), for the "Rüstsatz M1" 2x MG151/20 + 200 ammunition under the belly are already installed. 2x MG 151 can be fitted instead of the 2x MG 151/20.
At the top right of the variometer you see the "Drehschauzeichen" ( turn-view-sign? ) which shows the working of the de-icing-system of the armored glass.
See the pilots main-fuse-panel on the right side behind the compass, should be in all C-to-G-series. Additional UV-lamps(n) are installed for night flights.

This cockpit has the ZVK-FF ammunition-counter for the MG-FF/M installed.
The spare-parts-catalog from 15. June 1942 indicates a change in the armament from 2x MG-FF/M to 2x MG 151/20 with 350 rounds in thr right MG and 400 rounds in the left.
In case the MG 151/20 are installed, the SZKK 2 (Fl.47317) ammunition-counter should be installed in the panel.
This modification is from outside only distinguishable from the missing openings in front of the ETC 500/IXb (bomb rack).

OK, back to the cockpit.
Right side:
bf 110 f right.jpg

No big changes in the right hand panel (even it is a new panel...).
Left of the cockpit-light-poti(1) you find the turning-switch for the "Roland-Anlage" (only F-4) and it's control lamp below (also "Drehschauzeichen").
In the F-2 you might find the same turning switch and lamp, but with an additional lamp in front of the switch. Then additional position lights (zusätzliche Kennlichter) are added to the fuselage.
In front of those turning switch I guess the switch and the 2 control lamps for checking tire pressure.
You read right, the F-series has an electric tire-pressure-control.
The manual states that there are 2 control lights(one for each tire) in the cockpit and those are the only one I can find and have no real description for them, so I can only guess.

Engine instruments:
bf 110 f engine instruments.jpg

The only change here is from the double-oil-temp-gauge (oil-temp-in/oil-temp-out) to a single-oil-temp-gauge(oil-temp-in).
Good to see the mech. prop-pitch-indicator ( which is missing in CloD ).

And now a picture from the spare-parts-list, regarding the instrument panel in the cockpit.

Cockpit of the G-series:
First I will show you the standard cockpit of the G-series, then I will go into the subtypes.

Bf-110 G cockpit.jpg

This cockpit is mostly the same as the cockpit for the late Bf 110 F with MG 151/20 instead of the MG-FF/M.
The only differences I could find is a changed right hand panel ( the oxygen-bottle is now below the panel? )
and the use of the "Schwenkplatte Sp 2 A" (the same as in the Stuka) instead of the "Sp 1 A".

Bf-110 G Revi.jpg

The left and right front windows are also armored.
The only difference between this cockpit and the G-2/R1 with the 3,7 cm BK is the closed left ammunition-counter of the SZKK-2 (below the Revi).

The G-series cockpit with "Rüstsatz M5: 21cm BR"

Bf-110 G Cockpit right.jpg

No big changes here either. The plates for the power switch and the arm-switches(always on and armed) are gone for arming and disarming of the 21 cm BR.
The Button(7) for ermegency drop of the BR-tubes is changes to a switch (might be the same as in the F-series? See previous post: right side)

For the Bf-110 G with MK 108 I have found 2 cockpit variants and 5 subtype-callings.
Let's begin with the subtype-names:
First type is the original one with 4x MG 17 and then the subtype with MK 108 in the nose.
Bf 110 G-2 >> Bf 110 G-2/U9
Bf 110 G-3 >> Bf 110 G-3/U9
Bf 110 G-4 >> Bf 110 G-4/U9
Bf 110 G-2/R1 >> Bf 110 G-2/R3
Bf 110 G-2/R2 >> Bf 110 G-2/R4

135 Cartridges for the right and 120 for the left MK 108.

Now it get's a little bit tricky.
Since we have 2 pictures for the same armament dated nearly the same time (January/March 1944) but with differnent layouts of the cockpit,
I have 3 possible solutions.
First: The 1. picture I show now is a field mod allowed through the RLM with manuals, to change old type to the new subtype.
Second: Luther and GWF produced each a different version of the MK 108 subtype.
Third: Both of them are true.

By the first type with the MK 108 the "SSK 404/2" was replaced by a plate with 2 buttons and control lamps.
So nearly the same as the standard G-series.

Bf-110 G-2R3.jpg

The second type has also the "SSK 404/2" deleted, but a "SZKK-3" instead of the "SZKK-2" and only one switch to charge the MK 108.
