Replacing light seals
Old cameras often had light seals made from a rubber foam which degrades (more accurately disintegrates) over time. The best thing to do is remove and replace them, though this can be a long job depending on the number of seals, their condition and the glue used to attach them.
This Instructable is a very good guide for replacing light seals, but it doesn't go into a lot of detail.
Light seal dimensions
As I've repaired my cameras, I've made a note of the light seals needed. This information is presented here for reference, with no guarantee as to its accuracy.
