Hello, I have a window that has a strippedout crank system or operator and I would like to replace it. The operator has a number on the small arm that says 31538A and 1982 is stamped on the bottom with some patend numbers. Can I get this part?

This looks like our 39-031 operator. Check it out and let me know if you agree.
