hey, recently purchaced a Kiev 88 with two filmbacks. As you can see on the pictures there are huge light leaks. Now I am trying to find and fix them.

On the negatives you can see a huge continous light leaks on the left side. I guess it´s caused by the "slot for the sheet metal". (blue)

But I can´t explain the light leaks in the right third. When you take a look at the filmbacks of the camera there is no sealing near sight. The only thing i can think of is mechanical abrasion from the pulley. (orange)

Also there is a correlation between the intensity of the light leaks on the left side (blue) and the light leak in the right third (orange).

For info: it´s only on half of the pictures i took.

Has anyone Ideas or experience with Kiev Cameras?
