Misplaced Service Book

[ChrWh]

As we have just had Family over from canada, a big tidy up was needed, which i was not involved in....result of the story is that i can now not find my service book anywhere.

Is it possible to get a replacement?

Only a duplicate not an original item.

and will it affect warranty?
