sorry Koddos, i mean the knobs/leavers, who are one to each side of the throttles on that image right side of the mouse.

Those are levers for cleaning the oil filter.

If I understand it correct it has a rotating filter in which the oil is pressed. This filter can be closed through dirt or abrasive materials of the engine. To clean it, you move the lever from one position to the other to move a brush, that will clean the cylinder filter.
I took that knowledge out of a DB 601 E-G handbook. But I think the principle will be the same on a DB 601 A.

Just more workload for CEM.

Edit: It states Anlaßpumpen (starter pumps), which is wrong labeled. The Anlaßpumpe is below the hinged metal sheet on the right side of the Fuel selector (not Pumpenschalter).

Regarding 100 OCT fuel in the Book "Messerschmitt Bf 110, Me 210, Me 410" from Mankau/Petrick is written:
Page 24:
"12.7.40(GL)...GL has decided that the available 601 N for now only in the Bf 110 will be build in. With that the assembly (601N) for the Bf 109 will not be applyed within the series."

"19.7.40 (GL).. the existing 601 N engines will be used up for the change over for on the front residing Bf 110. With that the further change of the Bf 109 groups (at now 1 group changed) will be dropped. Bf 109 F-series keeps the 601N engine. New build Bf 110 will be build with DB 601 A."

Page 25:
"26.7.1940 (GL) Genst. oppose the further fitting of 601N engines on BF 110, except for the already changing ZG...."

"9.8.40 (GL) For the already ordered change of in all 3 groups Bf 110 and the already changed group of Bf 109 will be 70 assembly engines for monthly 30 replacement A/C Bf 110 and 10 replacement A/C Bf 109, as well as 30 reseve engines provided through LC 3. That means by 280 engines in action a reserve of 10%...."

Page 27:
"27.9.40 (GL) Chef-Genst. has decided that 4 Zerstörer-groups BF 110 be fitted with 601 N and to be maintained. The supply for the groups matches the delivery of the firm Mtt, Augsburg. [Augsburg produced at that time [8.40-8.41] the Bf 110 E-1, see page 324] from the remaining engines 40 engines are buffer for the Bf 110. All other engines are to be f1/3 reserve and 2/3 are fitted in Bf 109 A/C.

Bf 110 E-1 is still ordered 2/5 with Dackelbauch and 3/5 w/o Dackelbauch...."

Page 28:
"18.10.40 (GL) At the moment it is impossilbe to refit additionally A/C Bf 109 E, except the already existing group to 601N..."

"26.10.40 (GL) Until the end of october 1100-1200 601 N engines are delivered. Thouse engines are build in 4 refitted groups Bf 110 and 1 group Bf 109, additionally in different A/C of the reconnaissance group Ob.d.L. As reserve 130 engines has been delivered to LE. The rest is for Bf 109 F-1, F-2 and the Messerschmittproduction Bf 110."

Page 29:
"6.11.40 (GL) ... Genst. requests that 601N favorly be fitted in Bf 109. to make the engines available, Genst. agrees to let 2 month deliveries of Bf 110 be fitted with 601 A instead of 601 N, if the bf 109 equipped with 601 N can be ensured. Following positions must get N-engines:
1.) ending series of Bf 109 E
2.) Reserve engines for III./ZG 26, Erprobungsgruppe 210.
If not enough engines available, following groups doesn't need to be supplyed with 601 N respectively 601 N can be changed to 601 A engines: II./ZG 26, II./ZG 76. Since the delivery of 601 N in january will be higher, the Bf 110 production will switch to 601 N engines."

Don't forget that those early ones doesn't have any heavy armor like the later ones.
And in the "D.(Luft)T.2110C, D und E; Bf 110 C, D und E Flugzeughandbuch Teil 8B Einbau und Prüfung der Abwurfwaffe; Heft 1" from May 1941 on page 5 under "Beschreibung" (description) you find:
"Die Rumpfabwurfwaffe kann beladen werden mit:
2x SC 250 kg Bombe oder
2x SD 500 kg Bombe oder
1x SD 1000 kg Bombe oder
1x SC 1000 kg Bombe und
___________1x SC 250 kg Bombe.

Die Flächenabwurfwaffe kann beladen werden mit:
4x SD 50 kg Bombe oder
4x BD C 10 (BD 10 Bündel mit 5 SC 10) oder
2x S 125 (Nebelgeräte)."

If you count 1xSC1000+1xSC250+4xSD50 together you get 1450kg.
Add the weight of the armor platings from '41 in the Bf 110 and you get your 2000kg.

Or take the Bf 110 D-1: 1050 l Fuel + 106 l Oil in the belly tank and 2x900 l in the ventral tanks = 2956 l >> 2056*0,78 = 2306 kg and thats only fuel/oil! and I didn't add the weight of the empty tanks.
also starting weight: 7,1 t, by overload 9,3 t

So it can carry 2xSD1000 bombs!!
They even made the undercarriage sturdier for that by the C-7.
Even the C-1/B with their weaker undercarriage could be attached with them, but if you could take off in one piece from a grassfield is another question.

I have to pipe up here. Just because the manual states so it doesn't mean bombs above 500kg were carried operationally. I went through my sources on Erprobungsgruppe 210 (which was the only unit to use the Bf 110 as fighter-bomber in 1940) showed no bombs bigger than SC or SD 500 used.
It's a bit of a mystery why a dedicated Dienstvorschrift was printed just when Erprobungsgruppe 210 had just been established to test the usefulness of Bf 110 and Bf 109 as fighter-bombers (established July 1 1940). And that the amended version from May 1941 contained a more varied loadout list with heavier bombs is not that surprising, even though it must be kept in mind that bombs above 500kg were considered "special ordnance" and its use had to be ordered/approved by the Fliegerkorps.

[Kodoss]

@csThor: can you make a list of bomb load which was used by ErprGr 210?
I miss the SD2 for airfield raids may it be Bf 109 or Bf 110.
