IT LIVES !!
sound: flash of lightning...
the 50/50 mix of hydrogen peroxide and ammonia ate the fungus off the lenses. They are perfectly clear now. YEs!!
I actually split the other shutter I had, and replaced the defective rusted shutter blade. It was a perfect match.
Now I will try to fix the defective blade and reinstall it in the other shutter/lens. If I am not successful, I will have a parts lens for folks who need a part or two..
