Old knobs on new door?
As part of a remodel our GC purchased a new interior door; it's pre-hung and pre-drilled (2-1/8 bore, 2-3/8 backset). It's in the kitchen, and the other doors in the room (which are immediately on either side of it) have original 1916 plain white porcelain oval knobs. We would like to match the knobs, but nobody makes these anymore.
We have a set of knobs available, from another door which was scrapped during the remodel. But our GC knows of no way of using the old knobs on the new door. Is there any easy way of doing this? Can we buy a knobset which will fit on the new pre-drilled door, but which will allow us to substitute the antique knobs? Any ideas?
