1992 Milguard casement window bottom sash hinge

Thanks for reaching out to us! Your hinge looks like an older version of our 36-048. I am confident that this will work for your window as long as you replace the top and bottom at the same time. You don't want to mix old and new hinges.

As for the operator, I'd be happy to make a recommendation but I will need a more complete picture of the mechanism. I specifically need to see the base and the end of the arm, all in one shot. Let me know if that's possible.

Thanks! These pictures are helpful. With this new data in mind my first guess would be the 39-031 and 39-032. However, you should definitely compare the dimensions we show on our store pages to your old hardware to be 100% sure. These are no guarantee, just my best guess. Don't buy anything without double checking.

As for the weatherseal, there's no way for me to know at this point. I would require photos of that, as well; specifically, I need to see the end profile in undamaged condition. The video below will go into more detail.
