I have not seen any names or markings

Hello, thank you for posting,

You have older style "Sears" storm windows which are no longer made and the parts are no longer available. We do carry a top tilt for a different type of window frame, the 95-211. However you would need to see if you can adapt it to fit your frame because the legs on the 95-211 do not have the same dimensions as the ones you need.

I apologize that we cannot supply direct replacements. Please let us know if you have any additional questions. 

Dimensions for 95-211

No problem! Let us know if you have any future hardware questions.
