Well I rushed like hell down town to a camera shop for advice and the plate is ok as this is just where the miror reflects the image on to pass to the viewfinder.
What that means is I'll see it every time I look through the viewfinder but it won't show on the pics as the image deflects to another part of the camera.
I can tell you I was soooooo relieved. Drove like a bat outta hell to get back and get shaved/showered & out to the registars office.
I got there with 5 minutes to spare.
Will updat about the wedding later. ( I've only just popped back to get changed.)
