Sooo…
The library at Lincoln Center in NYC has 2 16mm copies available. Unfortunately, I have no way of scanning it. Is there anyone else near NYC that would be interested? I don’t believe we have a scan of it yet, no?

They also have one of the Raiders of the Lost Ark documentaries on 16mm as well!
