If I am interpreting your first photo correctly, your frame is the later of the steel types, fitted just before the chrome-on-brass screen was introduced. I believe there were 3 different profiles of rubber seal on the various steel framed screens, and the one you want slides in the central groove that you can see looking at the frame edge-on. It does not need to be formed around the corners for a good seal like the later brass frames. Jamie at the Seven Workshop lists it as part number B0402A, and I am sure he will send you a small sample on request. No Austin Seven saloon originally had a seal fixed to the body - always a bodge to get around this notoriously leaky area.
