It "looks" like the manufacturer of the windows is Warnock Hersey. They house was built around 1996. I am selling my house so trying to replace some of the broken ones where the thumb piece that sticks out keeps breaking.
The length of the latch is 2 5/8" (3" if you include the retractable end piece. The width if the top plate is 11/16". The height is 7/16".
Thank you for any help you can offer on finding replacement parts.
