The Flash Gordon release cannot count as a preservation, because it has had a DVD release. As the rules currently stand, it doesn't matter whether that release is out of print, a different region or whatever.

You may start a thread about this under the custom DVD rules. That means you may post details about the disc, methods used for conversion, even post download links for any unreleased DVD-ROM extras. But there is to be no discussion about distribution whatsoever - not even vague hints. As far as this forum is concerned, members are to buy the region 2 release and convert it themselves following your instruction.

This treatment is no different to any Star Wars projects, and I've edited several posts in the past for the same reasons. Here's one for example.
