anderson window crank L 31538

Hey there!

I'm afraid I couldn't cross-reference the number given here. Would it be possible for us to see a photo of the window open so that the operator's arms are fully visible? That will allow us to narrow down some options. 

Thank you kindly! I recommend you have a look at the 39-031 and 39-155 operators. Review the specifications below and see which one matches up with your old assembly.
