Hello, can you help me identify this seal?
It's an Anderson window for mid 1970's I believe.
Thank you

Can you show us a clearer picture of this seal's end profile? That cross-section view would be a huge help. Thanks.

This might be something like our 55-303, but the only way to know for sure is to compare the end profile dimensions. See the video below.
