I am not sure what crank to use for these windows. The handles(cranks) have been missing for a long time. This is a rental home. I'll send you a picture and matbe you can help and advise. Thanks,

Thanks for posting, Gary! Please take a look at our 39-268 Wood casement window operator with a brass finish. Does this seem similar to what you need?
