Looking for Mastic double-hung window sash lock

Handy Person from Rhode Island
Hello! I'm looking for replacements for the Mastic window sash lock pictured here. I'll be happy to provide any additional photos or measurements that might help.

We don't sell a lock that matches this, but I think one of ours can still work as a replacement. I will just need you to write out a few measurements for me. There are two:

The first is the distance is between the two installation hole centers. The second is the distance between the hole centers and the back edge of the sash frame. That will allow me to find a good replacement lock that doesn' require drilling new holes.
