Help finding locking mechanism

Sorry it took me a few days to get back to you. We have a 18-month-old and it's been crazy around here....

I took few pictures and took apart the locking mechanism to remove the part that's broken. I put a arrow on the part that's broken. On the back side of this broken piece it has the number 537.

Can you identify which part you'd like me to measure?

I really appreciate all your help on this

Unfortunately, this lock assembly has been discontinued and no direct replacement has been found.

We do offer the 38-099, which is similar but the dimensions are not the same. Your best bet would be to have a local professional come out to see if they might be able to adapt a lock like ours to work for your window. Thanks for posting.
