Simonton double hung windows

Hi there!

Thanks for reaching out to us. We're happy to look into this. We'll just need a bit more information to ID what you may have here. Can you show us photos of the pivot shoe? You'll need to fully remove the window sash to get a good look at it.

I'm not familiar with the part in your last photo, however. It looks like it may be damaged. Would it be possible for us to see an undamaged version from a few different angles? Can you also tell us the function?
