No part number on the window lock

Hello,

We do not carry an exact match for the lock shown in your photo, but we'll need a bit more information to determine if we can provide a possible replacement. First, we'd like to see the locking tab with your part uninstalled, as well as confirm how the lock is engaged, since there is no lever shown in your photo. If the lever broke off, is there an intact version of this lock you could show us from another window? We'll also need you to write out the exact distance between the center of the installation holes. Thank you!
