I recognize some of the parts in your photos, and will need more information on others.
Starting with the ones I recognize, see our 15-175 pivot shoe, Series 152 coil spring, 26-243 and 26-244 tilt latches, and 26-122 vent latch. We pulled up more media guides to help you on these. We don't have the exact coil spring cover, but if you need to replace them, you can use our 15-150D.
Now let's look at the window lock. I'm confident we can replace this, but before we recommend anything I will need you to give us the distance between the mounting screw holes, center to center, as well as the distance from the lock to the back edge. That will allow us to find what you need.
