Well I've got this thing back together. I might add that is was no small feat. At first the shutter would not trip. Some BOOB had been tinkering with it and had bent the long trip arm that extends from 11 o clock to 4 o clock on the right side, and it was not catching the little trip dealie at about 3:30 o clock.As it turns out that long arm is VERY important to be bent just so, as it has a lot to do with accuracy.
Now that the whole thing is nice and clean and wrokd like a new one, I have a question because I have no shutter checker. There are only 5 speeds on this thing--50, 25, 10, 5, 2. But I can barely tell any difference between 1/10 and 1/25. Or is this normal for us human beings? I wish I could get my hands on the technique for tuning shutter accuracy. It seems it would have lot to so with spring bending or lever bending, or both to fine-tune this shutter.
