I believe these could possibly be of US manufacture, but not sure. I have seen others in use. They require restoring, with one of the 4 sliding windows having a piece missing and the black rubber or plastic surrounds have gone rather hard. They are lightweight and the arms can be moved or unscrewed so they can be packed easier than the standard side screen. I had intended to use them on continental holidays when boot space was needed, using the conventional side screens the rest of the time. However I never got around to restoring them.
Siting unused in my garage for many years. Spare items that I never used myself. No warranty given nor implied and no guarantee of serviceability implied. Sold as seen. Being sold as downsizing house move forces sale.
For collection near Huntingdon Cambs.
Thank you for your interest.
