Crank handle replacement

Question

We don't know what kind of windows we have but we are looking for replacements for the cranks.  3/8 is too big but I'm not sure what the right size is. Here are some photos. That crank in the photo works great but it's the only one.

Hello, thank you for posting,

Your handle resembles the 39-148 Peachtree crank handle that has a 9/32" diameter gear bore that fits onto the operator spline. Please review the overall dimensions to confirm a good fit. Unfortunately we are not able to provide the crank operator. Let us know if you have any additional questions!
