I did just that,,I sent my $50.00 to the Heritage center and let me tell you,I am very impressed with what I got.The docs show that my formal limousine was delivered to New York on Aug. 2 1954, it was then transferred to a Chev. dealer in Altoona PA. I now have all the trim specs in detail.If you are contemplating doing this,,it is money well spent. Doug (in Sydney Australia)
