I don't think it's a dark bar. I think it is some kind of flare that covers all of the image except the extreme left.

Does it vary according to what direction the camera is pointed ?

Look at the release catch on your lens adapter to see if light is leaking in there. If so, stick a bit of black paper on the inside of the adapter to block the leak.

I tried that... With no luck. I posted a sample. The bar is always the same (form & size)

Well, just try wrapping a dark cloth around both the adapter and the lens mount of the camera. It could possibly be the famous light leak around the lens mount -- which again is said to be worst at the position of the release catch (the one on the camera).

The more I look at it the more it looks like a light leak.

Here is a light leak from an adapter. The subject is a very dark (badly underexposed) 35mm slide that I was digitising.

And here without the leak.
