Missing window operator

A contractor from St. Thomas, USVI says:
Good day. We are missing a window operator like the one above. The only mark is "Made in USA". the operator is 5.5" and the arm is 7-1/2" from the tip to where the arm angles. We need both left and right operators.

Thanks for posting. Start by looking at our 39-138 and 39-139. Let me know if you think these match what you need.
