Here is what I can come up with
pic 1 - the materials sample book with original swatches as used by Porsche
pic 2 - the headliner swatch
pic 3 - picture of an original 1970 headliner
pic 4 - Autos International headliner installed in a car I own
There are 2 possible variants on the headliner - grain on the vinyl and the perforations. Now Autos does not make the material, they cut it to a pattern and sew it together. The grain does not look very far off if at all off. The perforations are done in a slightly different pattern. Maybe I am just not very good at this Porsche restoration thing but the differences between factory original headliners and reproductions are not bothering me. Of course if someone makes a better headliner for the same price then i will buy.
