The slider and hinge in a steel window from 1929

Hello there!

Thank you for reaching out to us. I'm afraid we don't sell a replacement for this hinge. This window is just too old, unfortunately. I am very sorry that we won't be able to assist with this repair but please let us know if you have any other hardware questions.

I am afraid we don't know the exact term for this type of hinge. Your best bet may be a local mom-and-pop type hardware shop that's familiar with older casement windows in the area.
