Having taken apart a seneca uma lens circa 1898 to clean works I found that the aperature diaphram was a group of blades with no pivit pin.One of the blades was sticking but none are torn what ever oil they used on it had congieled (sp?)any one know how they go back in the shutter works without them. I have already timed the shutter and can use it on one of my graflex but want to replace the bellow and use it as it once was. They are flat round pieces with eliptics on both ends as long as a half dollor or pound coin is wide and about as thin as 80 lb paper and look like little handle bar mustashes. Also, does anyone know where to get new bellows? Turner Bellows wants premium to fab one even though they must have made most of the original stuff. This is a 120 camera and stops down to f-64
Do the blades have a hole punched in the end? On many American made shutters the end of the blade is punched out and the raised portion of the hole in the blade fits into a hole or slot in the diaphragm control ring.
As for bellows, I have been making my own for several months now. It's tedious but not that difficult. Once you realize the amount of labor involved in making a bellows by hand, you can understand why commercial bellows makers can charge what they do. You may be able to find a new-old-stock that will fit. I think Winfried said he has a source for some bellows.
