Replacement Sash Lock In White

How far apart are the centers of the screw-holes? Looks like we probably have something.

Also, how far are the screw-holes set back from the edge of the lock? What I mean is, what's the distance between the edge of the lock facing the glass and the center of either of the screw-holes? Give us those two measurements, and we should be able to find a match.

2-1/4" between the screw-holes, great.

Now I just need the backset measurement that I described in my previous post, to ensure that the lock sits the correct distance from the face of the glass. Can you measure that and send it to me?
