Does anyone know how to adjust and fix the RF of an Olympus Ace?

So I recently bought a little rangefinder called the Olympus Ace (AKA tower 19) from Japan. Basically it's a pretty uncommon interchangable lens rangefinder that was supposed to be olympus' cheaper M3. Unfortunately, when it arrived the rangefinder was beyond screwed. I've completely stripped it down ( it is a pretty simple rf mechanism) and gently cleaned all the surfaces, yet the rf patch is still just a blurry haze. It also seems to be significantly out of vertical alignment.

Has anyone ever worked on one of these before? Help!

If the rest of the camera works, the rangefinder would be of little worry. It would not be of much use except for the 80mm lens.

Take some pictures with it and post your impressions. I have seen various postings that the lenses are a bit disappointing for Oly (which means they would be pretty good lenses for other manufacturers ;-) ). My own tests tended to agree with that assessment. Nice images but not the razor sharp stuff we expect from Zuiko glass.
