Window cranks

Question

I was hoping to replace the window cranks on a few windows in a sun room at my house. I've attached pictures to hopefully narrow down what parts I would need. I can't find any part numbers or manufactures names in any of the windows or existing cranks.

Hello,

I would recommend starting by comparing the specifications of the 39-025 and 39-026 that use a 10-24 thread bushing to yours. If you notice any discrepancies, please write out your exact measurements and we can go from there. Thank you!
