I was disassembling a Copal (Polaroid MP4) lens and the shutter blades and spacers fell off their pins before I got the lens apart enough to see their positions. There are 6 blades and three spacers. It's obvious how 5 of the blades go, but the rest is a mystery.
Can anyone tell me how to put them back properly? Or where I can find a diagram or photograph?
Sounds like your shutter is one of those that has the "extra blade". I've worked on a couple (Prontor SVS, for example) that have an extra blade that doubles up on top of one of the other blades. Look at the blades: is one of them different?
