The original track would have variable density, which has probably survived as either a fine grain or dupe. It’s fine, but I don’t believe is what it once was.
Before researching further aeons ago, I somehow thought that Peter Ibbetson was a film set in 17th century Dutch New York.
It isn't.
I was led to this film, probably 40 years ago, by David Shepard, as it was one of his favorites.
It's an oddity, albeit a beautiful one, anyway one looks at it...
