The VF was a bit foggy so i took the top off to clean it. The front and rear FV windows and lenses cleaned up nicely but the real problem is the FR half-mirrored glass. What might I do to improve it?  |

Just clean it carefully like the other surfaces. I have cleaned a lot of these half-mirrored glasses in rangefinders of the 70ties and I have never harmed one.
I know that others have other opinions and there might be a dispute about this issue. The glasses in older RFs (60ties and older) are more delicate. |

I've taken the metal right off some, but I do think they were earlier than the QL17. |

The point is that some cameras were stored under unsuitable conditions, like too much humidity, warmth, smoke etc. All these factors exert their influence on internal and external camera parts. I have seen mirror coatings vanish from just looking at them, while others would have survived heavy grinding. The ones in Konicas for instance are more vulnerable than those inside Canonets, by rule of thumb, so any individual cleaning procedure depends on the actual state or circumstance of the current problem that has to be solved. Hazy coatings and mirrors affected by fumes, chemicals or fungus can hardly ever be restored to a condition like new. |
