BTW regarding the first post, I just confirmed that Bf109E-4 did have shell ejection from the wing cannon.

I've been looking for a visual reference and can't find one. I can't seem to find my Aero Detail on the 109E. I have a found a couple of conflicting pieces of writing regarding whether the cannon cases were ejected or not. Do you have a photo or visual reference of this?

109e wings

Many thanks Ring. I figured the Aero Detail would show it.

HUH !!!
That's not the MG-FF shell ejection port !
The big bulge contained the ammo drum, next to it toward the wing tip lay the MG-FF itself, which ejected the shells toward... the wing tip !!
The expanded cases were collected in an ammo box placed between ribs R3b and R4. The shells were not released in flight.

look at photo 60 and read the text for it.

hummm i have been studying the 109 design for a few years

so i know what i'm talking about when it comes to this particular bird

The MGFF wing installation was similar on the C-3, D-3 and E-3 and exactly as i describe it. The shell were removed on the ground through an access hatch.
The acces hatch is barely visible on picture 57 of the same book

bah, what does Butch know

I heard that 1 min after his birth Butch felt in the 109 book collection of his father and learn to read German during the 2nd minute

Bonne Année au passage

You know I would tend to agree with butch on this. I knew there was a hole down there but it always bothered me because it seemed to be on the wrong side and so far back but I went with a shell ejection port when I saw the aero detail book's explaination in a store. But I think butch's idea is much more likely and it does ssem more logical considering the way the gun is setup.

Pyro, lets leave Bf109E4 without shell ejection for the MG-FF.

I thnik you made the right choice

From the 109E armament manual :

Ok, so no shell ejection on the 109E. Just curious, but do you have any idea what that port is for Butch?

butch2k · « **Reply #28 on:** January 03, 2005, 12:36:15 PM »

AFAIK it was used for cooling rear parts of the MG-17s mounted on the E-1/E-8s, in some cases you'll even notice some powder stains.
AFAIR it does not appear on the C-1s or early D-1s.

That is a really unusual design element. Even if you postulate that not all E models used the storage box it is physically in the wrong place to be an ejection port (it would have to be located somewhere in parallel with the magazine buldge and not immediately to its rear.

Butch's diagram shows that it is located underneath the firing solenoid so it may have something to do with cooling that mechanism, or just a coincidental location for general cooling or perhaps a means to reduce carbon fouling in the compartment for some functional reason.

You would assume that you don't just add something like that unless you really need to.
