Window locks

Hello.

The sliding windows in my sunroom are missing their handles and locking mechanisms. They were not there when I moved in. The pictures that show the handle/lock are from another condo unit. Looks like a small version of a patio door handle with lock. I do not see a manufacturer's name on the window frames. (The casement windows in the unit are Norco brand.) Hoping that you can help me find the correct replacement parts. Looking forward to speaking with you.
Thank you.
