I just looked in the Judges Standards book and there were two types of seat upholstery for the 28-29 Tudor. Plain and piped (rolled pleats). The 1928 had piped seats (3,3,8,8) and the 1929 had the plain seats. In 1930, the Tudor came out with the piped seats (5,5,11,11) again. According to that, I have the wrong seats (piped) in my 1929 Tudor.
