Now here's something really crazy. I just went way down deep into this shutter. To the point that shutter leaves are coming off their pins and fell out. I've got a picture of how they go, so that much I'm happy enough about. But I've got a leaf leftover. There are 5 pins, and the picture of the shutter I'm looking at on the web has 5 leaves. So why do I now have a 6th one leffover? BTW. Somebody has been into this thing before. The original problem was that the mechanism and timer worked OK but the shutter wasn't opening. Where in the world did this 6th shutter leaf come from? There's no place to put it back in. All the pins are taken. Strange.
