Crank Handle and Casement Operator (?)

A home owner from 17554 says:

Hi - about to try and sell our house, but all of the window operators are old and worn down. The crank handle has the marking OP05-1509 and I think the casement operator marking is OP05-7540-03, but I need some with the hole on the right and then some with the hole on the left.

Could I get some assistance with identifying these parts?

Also, do I need any extra parts when I replace the handle and the casement operator?

Hello,

We'd be happy to research your replacement options but we'll need to see a photo with the window open and the operator arms that move the sash in and out fully exposed to identify your hardware. Thank you!

Thank you! This operator resembles our 39-325 and 39-326 but make sure to compare the dimensions on our product pages to your hardware to confirm that these parts will work in your window.
