Can anyone identify this lock?

That is a seventies through eighties trunk lock, I don’t recall exact years it was used, but any lock smith can get you a new replacement.

ES1143 is the factory key code used to cut a key for this lock. If that lock pictured is original to the car, its key will fit the glove box as well.

If you get a replacement lock, the old lock’s pins & springs can be transferred to the new one so the same key will once again work both glove box and trunk.
