i take it you've tried google kev !!!
It rattled like a maracca and didn't AF properly anyway which is why I took it apart. No point paying someone else to do it when I can. Nexttime I'll leave it all until after dinner so I'm not interrupted though.Scrap it and consider it a lesson well learned. I don`t think any repairer will take it on if its in bits.
Take another one apart, pay more attention and take photos?
On a semi-serious note, are there any 'for spares' for sale on the flea-market?
