Locating Dad's old 1931 Model A Roadster

[JoelsBuicks]

Hi, I'm trying to locate a 1931 Model A Ford Roadster that my Dad sold around 1972. He sold it to Tulsan Bill Darnell who did a complete restoration and then much later sold it to an unknown person/collector in Arkansas? - maybe in the late 90's. It began life as a Standard but Bill's restoration added the Deluxe package, I'm not sure just what this means but it is what Bill told me. It was the tan color with VIN A3983071 and

Original Title Number D857587.

If you know about this car or know how I can go about finding out who owns it or where it is, please let me know. I spent a lot of time pretending to drive this car over 40 years ago and my interest is in buying it if it is for sale.

Thanks!
