Thanks, Howie - I checked on 1591 and the interior is/was Medium Gray Nylon Seat Biscuits, Deep Gray Leather Bolsters and Medium Gray Welts-that's interior 2G5K.

What you picked up was apparently 1E6L - Deep Gray Leather Seat Biscuits, White Leather Bolsters and Deep Gray Welts.

The Dealers Invoice for 1591 shows it was sold to James Motor Co., Hays Kansas with no specified customer.

Regarding Alfred Epstein - I checked the Mark II Encyclopedia's list of original owners. There were three Mark IIs sold to people with the last name of Epstein. One in San Jose, CA. one in Coral Gables, FL and one in Ft. Wayne, IN. Alfred Epstein was not one of the Epsteins listed.

...and of course I searched our records, but I found nothing on Alfred Epstein.
