Hi. I was wondering if anyone has any ideas on where to find obsolete Peachtree window parts. I am looking for "spring catches" or latches for AE type casement windows serial G4589 (1989 vintage). I have found a few places that at least have photos of them, but none are available. I find it ridiculous to replace perfectly good windows because I can't find the hardware to fix them with. Any thoughts????

Thanks in advance!
