E, the problem is the gap on the bottom of the film gate by the bottom roller. It comes from the previous image on the roll. Not from the image that the reflection shows on. If you take the processed film and lay it on the film gate you will see that the reflection lines up with the bottom roller.

Thanks all for your input.
Carlos the image is upside down to the film no? So the top is where the problem is.
I was thinking of filling the gap with something... I can live with it of course, but if I did fill it, I wonder what I'd use. I was thinking about some sort of foam. 

Anyhow... thanks.

On my 3.5F, the roller is virtually level with the film guides.
Logically, the roller would be level to within a couple of thou' to
prevent the film bending away from the guides as it rolls tightly onto
the spool. Higher than that and it would lift the film off the guides
and lower than that, the film could be come scratched or kinked as it
moves over the guides. There must be a tolerence listed somewhere (in a 
repair manual?). Are these rollers adjustable by shims etc or are
different diameter rollers used to suit the height of the film guides?
The lens would be adjusted for focus on each camera so the exact
dimension of the film guide to front face of casting would not
necessarily be that critical. I guess parallelism would be more so.

There seems to be no adjustment for the roller postion. The brackets that hold them are located by the camera body, that is, you push them in as far as they will go and tighten the screws. Of course, you can tighten the screws with the brackets pulled out a little but then there is nothing to keep them parallel so I don't think this is an intentional adjustment. All the rollers are the same, that is, there may be different rollers for different models but not a selection of diameters for a given model. The ends of the film rails should prevent the film from touching the edges of the mask in the film gate. Whatever is the case I have never heard of a Rollei scratching film, at least not one in reasonable repair.
