I'd be happy to post some photos of the restoration if anyone's interested - it was a complete nut and bolt job over the course of the past year, and the camera was left in the workshop and used whenever I remembered!
If you have no luck with a full circuit diagram, I have some circuits in a workshop manual covering your model.
On ebay there is a seller vpk1 who has manuals covering your model on a CD. I don't know if he has a full circuit but you can contact him by email

He lives in Huddersfield. Yorkshire UK .
His current CD on ebay is item number 390316456532
