None, I know you had a few correspondences with this Steve Leggit, so maybe he told you something I don't know about.

This is what my inside source told me:

-SW was selected in 1989

-When they asked for a print, Lucas dragged his heels, talking about restoration needed (probably around 1992, 1993, when they were about to begin work on the SE)

-By the time he gave them a print, it was the 1997

According to the LoC librarian Zoran Sinobad, they didn't accept this, as it was in conflict with the legislation. This echoes what Steve Leggit also said.

So, it seems they never had it.

Furthermore, the condition of the copies outside the NFR, in the copyright depository, is not in good condition. ANH has some scratches but otherwise seems fine, but ESB has severe colour fading. There is no info on ROTJ. There is also a 1979 print of SW with subtitles for the deaf, with no info on that either.
