Thanks for reaching out to us. I'm afraid we don't have an identical match for this sash lock. Can you write out the distance between the two installation holes, measured from center to center? Can you also write out the backset? That's measured from the center of the installation hole to the top edge of the lock. 

Thank you very much! This reminds me of the 90-272 as well as the 90-072. Have a look at the specifications for each and see what you think.
