Gazelle? Does anyone know anything about them?

From the Guilty thread:

Hi Gaston, Yes, this frameset started life as a factory built Gazelle. If you look through some of the pics relating to this frame, you will see the original. It's poor condition needed a lot of work to breathe new life back into it. As you can see, I have not repaired the frame along the lines of the lugged style it once was. So whilst it appears a little different to it's original form, it still carries the Gazelle stamped ends and seven of its original tubes including the forks. Is it a real Gazelle? I think so and my friend Greg who owns the bicycle is a big Gazelle fan, he also likes It. Maybe it breaks a few stuffy Eroica rules but why be a purist when you can be a rebel. ...
