Hullo Damon,
Jack is completely correct re rivets being used for the bedknife.
I've just gone to the shed and checked my Imperial and there are six or seven blind rivets across the face.
I shall follow your restoration closely and perhaps gain the confidence to attack my own.
I've said it before, but I cannot fathom people simply junking these small pieces of our history.
Cheers & good luck with your efforts.
