On the original the material seems to be a canvas type material wrapped around a plastic/rubbery material. On most Javelins I would imagine this material has aged a fair bit. This is what we are aiming for:

Obviously not in black/brown/grey pattern, though this supplier does have the material available in plain black and red http://www.automobiletrim.com/door-seal-fabric.html (No 10 is what you need)
Peter had a similar issue with aged rubber, and I volunteered to have a poke around the usual suppliers to find a suitable replacement in an appropriate colour. A piece of the original seal was sent over, and the digging began to try and find something appropriate in a light brown/beige colour.
There appear to be two options. The most original that I could find in the right colour was sourced from Woolies Trim, this material:

http://www.woolies-trim.co.uk/p-1460-coach-lacing.aspx - note the thick centre section which wraps around the piping, and the thinner outside sections which can be stitched and will fit into the gaps required.
You also need a piping to go down the centre and get it to take the correct form. I chose a neoprene extrusion as it will be compressible, but also will form tight radiuses (radii?) without distorting in the way that a hollow rubber pipe might. It will also take up a bit of squash when the door is closed, improving the seal and avoiding draughts. Because it is contained within the coach lacing material nobody will ever see what is inside, so hopefully no points lost at concours there
The other option we found, as fitted to Keith's Javelin on investigation, was this material: http://www.woolies-trim.co.uk/p-1273-fu ... luder.aspx which looks like it would work, though whether it would be concours original is hard to say. It is also bonded around a rubber tube, so may distort around some of the tighter corners required to fit the door gap. It certainly seems to do the job, and is available in a much wider range of colours to suit interior.
Worth documenting, as this was quite a challenge, and I think we have found the solution. I will have the material in my hands from Woolies within the next couple of days and will update on how it feels in the flesh.
Jack.
