No offense, but your English doesn't sound very good. What is your primary language? What country are you from? If you prefer watching the original trilogy in your own language, it would nice to know what is is, unless you prefer watching it in English.
Most people in originaltrilogy.com don't post their fan edits or preservations directly on the threads because of fear of copyright law. By making it harder to find, it's easier to circulate. I know that might sound a little crazy, but its no more crazy than your preference for versions of star wars with bad video quality.
Someone uploaded clips of the Puggo Grande and the Pug Strikes Back, if you want to check if the quality fits your standards.

I might be able to pm you links to the Puggo Grande and the Pug Strikes Back, but there are no guarantees that the links will work.
Remember, google is your friend.
