Window Vent Stop

Hi,

I have a broken window vent stop I am trying to replace. I'm wondering if you can match the part so I can buy a replacement. I can send pictures if that would help too. The vent stop I currently have is in pretty bad shape.

Thanks,

Mark

I've attached some pictures to help better determine what parts we need. The vent lock has no additional markings on it.

Thanks,

Mark
