I just found your site and hope you can provide some information. I'm an appraiser working on an estate. No body has any knowledge of the vehicles but I'm sure your group can help me with this one. It's a Mark II, serial number C56D2874. I've determined from previous posts that this is a 1957 Mark, from the "D" in the number and was the 1873rd Mark built. Does this look correct? The car has a little over 49,000 miles. The car is painted white with a black and white interior. Any information anyone can provide would be greatly appreciated.

Thank you.
