Hello,
We'd be happy to look into this for you but we would need to see a photo of your operator with the window open so that the arms that move the sash are fully visible to compare to our inventory. See the videos related on this page to assist you. Thank you!
Your casement lock resembles either the 38-075 or 38-170 depending on how the dimensions and linkage that connect to the keeper compare to yours. We also offer the 38-039 keeper for these locks.
If you need a new operator as well, we'll still need to see the arms that connect the base shown in your first set of photos to the bottom of the sash to compare to our inventory.
