What kind of shutter issue is this?
I just developed two rolls of Tri-X yesterday in R90 1:50. This shot is from a Leica II which was performing fine a few months ago.
Notice how the image is dark in the middle. It is a bit more pronounced in some photos, and absent in others. I did two rolls at once, and the roll from a different camera didn't have this at all.
I'm no shutter expert (besides wrecking them) but can anyone tell me how a horizontal focal plane shutter would cause something like this?

A very distinctive symptom. A sticking shutter curtain which allows more light to strike the film at a certain point in its travel. When you press the shutter release the first curtain begins to open. Shortly after that the second curtain is released and begins to follow the first. Other than a short time parallax between the two motions the travel of the two curtains must be at the same speed. When the second curtain does not move smoothly (sticks) you get the distinctive exposure pattern seen in the sample. If the problem should be reversed and the first curtain sticks then you would see a band of reduced exposure.
Check to see that the grooves that the curtains run in are clean and there is no foreign material there. Another possibility is dirt in the gear train that controls the shutter.

Gerald gave you an excellent explanation. I'd suggest it's time to take or send that body in for a Cleaning Lube and Adjustment. Leica's factory service HQ is in Germany. There's a bunch of good info on how to access that service, paperwork requirements, etc., here
although come to think of it, you may have a certified Leica repair specialist right in your own neighborhood. Silly me eh?
Without guys like John Coltrane, Count Basie and Duke Ellington, life....would be meaningless.
i'm unclear -- is this picture cropped out of a horizontal frame, or is it a full frame on its edge--turned vertical?
If what you are showing us is the cropped middle of a full horizontal negative then, yeah, your second curtain may be hanging up in the middle of its run. CLA advised.
If this is a full frame, just vertical, then I'd have to ask if the dark band extends through the blank spaces between negatives, because there is no way a camera with a horizontal-running shutter is going to fog a negative like this, if this is a full frame, not just cropped.
scan three negs, with outside border areas, and post that-- makes analysis much easier.
Also, Leica will not service a II. You will have to send it to an independent shop. Essex in New Jersey does a good job.
If the shutter travel is parallel to the long axis of the sample image, and it is on all frames, but not in the short rebates, I'd suspect a (badly) perforated shutter blind.

Thank you for all the replies. The original photo I posted was shot portrait. I've attached two more photos - shot landscape - with the same problem.
It's fine if Leica doesn't service IIs anymore, I know of a few places I can send it.
I wish I could do it myself, but I'm positive I would destroy it

Your Leica has a horizontal shutter, it wouldn't cause a line like this if it was hanging or slow. Most likely a light leak somewhere.
Surely a light leak would cause a white band? Is it possible that there is some frayed material or a lump of fluff stuck to the leaning or trailing edge of one of the blinds?
I had exactly this problem with my M4-P. Although the effect on the negative was a little different which may be because I've darkened the attached image to make the problem more pronounced. It only showed up with faster shutter speeds where the gap between the curtains was narrow and being almost spanned by the fluff.

Hope this helps.
Yeap sorry you are right I was a bit sleepy and didn't take a closer look at the set of images. I hope you get to fix this, its a nice little camera.
