The Demonstrator was never a true Demonstrator anyway. It started life as Seaboard unit that got rebuilt into an E6 partway through the 1939 world's fair. I may need to add an E5 B unit. Hard to decide as there are so many other great offerings right now from Sunset.
I for one would be in for an 1939 A-B Seaboard Worlds Fair "E4" unit!
