This is pretty interesting, does your dad know if those prints went to Fox or up to Lucasfilm when the transfer was done? I always wondered where they ended up.

He's pretty sure they were returned to Lucasfilm. Either that or ILM. But, taking into consideration that Lucasfilm has an archive, they're probably there. Interestingly, the version that was put on home video format was not the first transfer they did. They were accidentally shipped a theatrical print that had a green tint on all the reels. They corrected it as best as they could and did a dupe of that. When Lucasfilm realized what they did, they sent them the correct reels and a proper dupe was made.

I'm wondering who did the widescreen transfers for the Japanese widescreen version etc, since they came off the same print.

... and why the pre-DVNR version found on THX Wow! and the Technidisc widescreen never got a good quality pressing. IMO that's the best NTSC master...

He wasn't there when they did the LD release. I recall we moved from Michigan (where CBS FOX was located) before my younger sister was born in 1989.
