Hi there. I am unsure of the brand of windows but here is a pick of the hinges. I need 2 sets. Maybe that helps. I originally thought they were Pella, but now thinking they are marvin?
Thank you!

Hello,
I agree that your window appears to use the 39-175 Pella operator, which indicates that you have Pella windows. Take a look and compare our assortment of hinges here and compare our measurements to see if you can find a match. Thank you!
