Missing and damaged window parts

Hello there!

Thanks for reaching out to us. Start by taking a look at the 26-243 and 26-244 tilt latches. The pivot shoe resembles the 15-177 which uses the S152 coil springs. As for the pivot bar, I wonder if you could have something like the 26-226 or 26-352. Review the specifications for these parts and see if they match up with your old hardware. 

Unforutnately, knowing the pivot bar does not tell us the rest of the parts your window uses but I agree with Emily that your photos resemble the 15-177. Ultimately, you'll need to remove the pivot shoe and tilt latch from the window to confirm the specifications below match up to yours.
