Attached is a picture of my HURD window crank. The Sash Keeper was missing when we moved in, and the crank works but doesn't stop once the window gets nearly seated like the other windows do. What would I need to order to fix the issues (besides the Sash Keeper)? I sent a picture of the other side window so you can see the Keeper shape. I'm pretty handy when it comes to mechanical things.
Thank you.

Hello there. This operator looks like either our 39-253RB or 39-439B. The difference between them is shown in the video below. For the keeper, Hurd casement windows have been known to use our 38-144 Sash Lock in the past, which uses either the 38-276 or 38-277 Keepers. See if this hardware matches up.
