Thanks for posting. To start out, your top tilt latches look like our 26-243 and 26-244. Please compare our pictures and dimensions to your existing hardware to confirm. As for the balance, our Series 775 looks like it would be a good match. From your photos, it looks like the balance hooks at the top of the window. Release your bottom shoe by placing a flat screw driver where the pivot shoe goes and while releasing it hold on so not to have it spring up. Then you should be able to unhook it from the window.
