Replacement crank for casement window

Question

Greetings.
I would like to replace the 2 cranks on my front bay casement windows. I was not able to find any identifying markings. Hopefully you could help. The measurements on the window itself are 16.5inch by 55.5inch

Hello,

Unfortunately, your GU operator was discontinued but take a look at the video below where we replace it with the 39-316 and 39-317 operators. Thanks for posting!
