Sliding Window Latch

I have a broken window latch that I cannot identify. I cannot find any markings on the windows or frame. Cheap single pane (pain) windows with broken latches. I have two of them. The separation between the screws is 1.5 inches. I have not found any latch with this spacing. The latch is spring loaded to close automatically. Could you recommend a replacement part. It doesn't matter if the seraration is different, as I can drill the frame easily.
