Do you sell these window locks?

Hello there! Thanks for reaching out to us. I'm not sure if we'll have a suitable match for this lock. Can you write out the distance between the two installation holes, measured from center to center? That will allow us to confirm. 

Thank you! Our 90-274 measures 2-1/4" on the installation hole centers. The backset is 11/16" and the sweep differs from your old lock, however. I can't promise this part's functionality but review the specifications and see how they compare with yours.
