Help with identifying original owner

You have the VIN #
You can get more information with that than what anyone else can provide here.

I obtained a repro of the orig window sticker from Ford which indicates the orig dealership that sold the car brand new.
I contacted the dealership [they are still around] with the VIN and they provided me with the orig owner along with copies of some orig service records that they had on file.
Instead of a window sticker you can also get a “Deluxe Marti Report”. That will also give you the original dealership info.
Maybe this path will work for you if the dealer is still around and “the right person” listens to your ask. I got lucky and maybe you can to.
