Graham,
I suspect you may be correct and the spring is distorted. I am fairly sure that when wound into tension, the spring is just about flush with the outside of the 2 flanges. I have been through my photos and can't find anything more helpful. There is this article (Thanks Esses A7 club) but I guess it tells you nothing you have not already discovered. https://ea7c.org/window-winder-repair/
