Casement window operator assembly

A home owner from Clifton Park NY says:
Windows do not have manufacturer name. But the crank handle inside has part number of 361490-5560062 and says TRUTH. From the Truth hardware website it does not match either Maxim or Ellipse as far as I can see. Could you please tell me what this part is and how I can get the entire assembly?

Thanks.

Hello,

We'd be happy to confirm if we carry a replacement for your operator but we will need to see the metal arms that move the sash in and out to identify a replacement. part of the arm is shown in your send photo, but not enough for me to make out a replacement. Thank you!

Hello,
Your GU operator has been discontinued for quite some time but take a look at the video below to see how our experts replaced it with our 39-315 and 39-316 split-arm operators. Please let us know if you have any other questions.

Thanks. I have added photos of metal arm. Please let me know if this helps identify replacement.
