new operator crank

Question

Need help getting the correct crank replacement for my aluminum awning style casement window. The home was built in 1948. I'm not sure if the window is original. I can't find any markings or names on the crank or the window.

Thank you for the detailed images! They are a huge help. Take a look at our 39-350 and see if that is a match for your operator. Compare all the dimensions with your sample to be sure.
