>crystal knobs that match my originals>
I know the ones that Crown City sells and they are beautiful. For my clients
w/ a limited budget, I get them for less than $20/pr from Wm. A. Kilian
Hardware in Philadelphia: [log in to unmask]
They also sell Baldwin passage latches that accept a knob spindle.
Not accurate historical reproduction, but effective and quite nice.
Good luck
