I will post some pictures of one seat and also one door trim to show the wicker pattern, do you have a good link to where to put the pictures?
I also have to tell you how important it is to try to contact the previous owners to get the history of the car.
My car was not a barnfind, but it was found outside a small cottage here in Sweden, when I got in around 1976. One big problem was that I did not have any registration number, I had the old style of tax holder we had long ago in Sweden, but it was empty. Since we changed to a new registration system in 1973 and the car was off the road then it was impossibleto trace it with only the chassis number. The old system was based on local areas, like the english countys, and my county were I found the car was Östergötland. It must have had an E-registration I hoped. In 1950-60 the swedish police sold a register of all cars registered in a particular county for a specific year, so I found on Swedish Ebay a book for my county for 1962. It was a list of around 70000 cars. The system was in numerical order starting with E1 for the governors car, E2 for the bishop and so on. The book showed the number, year, make (no model) and owner and his/her address. Luckily for the year of my car 1954 Triumph only made TR:s. So after going through 70000 posts I ended up with two Triumps 1954 and could then ask for a copy from the Swedish Archive where these registers are now. After a week I got two copies, but of course they were the wrong cars. Back to square one. Another book on Ebay and I found a similar book for 1958, this time with two counties D and E-county, together around 100000 cars. Looking through these, quite a few hours work, I ended with another two from E-county. One week later I had two copies in my post box, the first witch chassi number TS538L (wrong again). But the other was my car TS528L, and now I have an identity and previous owners of my car. I looked up three of them that were still alive, well above 80 years old. They were very surprised when I called them and told that the car still existed, one of them was the second owner of the car and had a lot of stories to tell me about it, which I took notes of. I asked him about the colour of the car and he remembered that it was a very light green colour, I told him that it was Ice Blue, but he said it was definitely a green tone. I then told him that the colour I found on the car was orange, and he replied: Oh yes I painted i orange 1957 the day before midsummers eve, he thought it was a much more sporting colour. "You cant imagine how many girls I have had as passengers in that car!" So before its too late, try to contact previous owners and get their impressions and stories about your cars.
