WHAT DO I HAVE?

MY FATHER WAS A BUICK DEALER AND SOLD THIS 31 BUICK NEW. THE CUSTOMER GAVE IT BACK TO US IN ABOUT 1970. WE DID A PARTIAL RESTORATION THEN AND KEPT IT ON THE SHOWROOM FLOOR FOR YEARS.
WE HAVE SINCE SOLD THE DEALERSHIP AND, UNFORTUNATELY, IT IS GOING TO POT UNDER A COVER IN MY GARAGE. MY DAD'S MEMORY HAS GONE VERY BAD, SO I NEED SOME HELP. WHAT DO I HAVE?
