Sliding glass door lock mechanism

Thanks for reaching out! I am confident that we can supply you with a replacement mortise lock for the one you have pictured here however, I'll need a bit more information. 

This lock looks pretty similar to one we carry in our inventory but to be sure that it will work as a replacement, I'll need to see a photo of the body of the lock as well. 

Would you happen to know the brand of the door and/or the mortise lock?
