Crestline Replacement Sash Lock

I moved into a house within the year with older Crestline windows. One of the sash locks broke (recessed, sits flush with the sash). It has a spring-loaded ball that no longer stays locked. As a result, I'm looking for a replacement in order to conduct a repair. Please advise as to the product I should be getting. Here's what the identification number on the window appears to be (also pictured in attachments for your reference): L28193Y27C3M
Thanks!
