Weatherstripping

These pictures show my weatherstripping at the bottom of what I believe is an MW Window. They were made in Rocky Mount Virginia about 30 years ago. The windows are in great shape, but I would like to replace this aging weatherstrip. Pictures show the base of the weatherstrip and the round body that has been "smashed" over the years. The third picture is the round body with a pencil gently opening the body. If you have something I could use to replace these I would greatly appreciate it. There are no identifying words or numbers anywhere on any of the windows. Thank you for your time.
