threw out my window hardware

Thanks for posting. Do you need the lock and operator, or just the missing lock?

If you want the operator, could we see the entire part? I can see it's based in your second picture, but I would like to see the arms, as well. I would also like it's dimensions to be sure.

As for the lock, it's really hard to say what you have without seeing the original. I don't suppose there's an identical window elsewhere in the house? If not, start by looking at our 38-075 and 38-089 keeper. See if any of these parts match up to the dimensions and hole spacing on your window.
