Re the warranty - probably a long shot it is a Mk1 and I am no way the original owner.
Re checked it this evening in my garage so max 4m but got a full movement of say 25mm each side of centre.
If I was bright could work out what that would be over 25m or so - but at least I know it is doing something so not as depressed as yesterday!
Thanks for your help!
