There are no visible names, numbers, or markings. Dimensions:
Total height: 1 5/8"
Dimensions of top: 15/16" x 1"
Top to center of screw hole: 7/8"
As you can see, it broke in half where the screw attaches it to the window frame.
Thanks,
Bill

Hey, Bill, thanks for contacting us. Have you seen our 18-125? This looks pretty similar to your top sash guide, but compare the two and let me know what you think.
