need new window operators. Not sure of the corrrect replacements

Thanks for reaching out to us. You're showing us a couple different things here. Your photos display both the hinge and operator assembly, but I can't see enough of either one to make a recommendation.

Can you clarify which of these parts you need, assuming it's not both? In either case, can you show me a clear photo of the part you need out of the window? This service requires clear and unobstructed photos of all parts you want to replace, which in your case necessitates removal.
