Want to replace this window crank

A home owner from USA says:
As per the attached picture I need to replace the entire crank system for my casement windows. I have 6 to replace. Do you have ones similar to these.

Thank you

Thanks for posting, Jo Ann. Have you seen our 39-031 & 39-032? These appear similar to your own hardware, but I can't be sure. Check them out and let me know what you think.
