the operator I need is from a roughly 20 year old Wenco casement window. From the inside of the house , it is the one to open the right window.
I need two of these and one which operates the left side window looking from inside the house.

Hey, thanks for posting. Take a look at our 39-028E operator. I believe this is a match for your current part. If you also need the opposite side, see our 39-027E.

I have the same patent for our window cranks, and I need to replace both, but was wondering if these have a comparable folding handle casing??

Hello! The operators that Dave Sr mentioned are both compatible with our 39-205 folding handle. Hopefully this information is helpful to you, but please feel free to reach out if I can be of any other assistance.
