Old cast vent locks - where to find?
I have a few windows with what I've determined are called vent locks, or window stop ventilation sash locks (per this site: http://www.kilianhardware.com/wistvesalo.html). I see a few of the more curvy decorative variety online, but none like these. Anyone know where I can find some to replace the missing ones? I suppose if I want them all to match I could order replacements for all the existing ones of the curvy variety, but they aren't cheap that I can find.
