Hello Everyone, I was given a Voigtlander Vitessa T that was previously taken apart and I am trying to figure out how the shutter leafs are supposed to be arranged. Most cameras that I have seen have 5 leafs but this one has six. I cannot figure out where this sixth leaf goes. It is narrower than the rest and does not seem to have a purpose as the other five shutters leafs completely cover the opening. Does anyone have experience with this setup and does anyone have any pictures and instructions of exactly how these blades should be oriented. I appreciate any help.

The short blade goes over the first blade you put, but it has to be added after you put all the large ones. It's like that, don't ask!
Have a look to this camera I've repaired. It's nearly the same. |

I believe it is a cappping blade to insure no light leakage from any blade movement..Don |

Does it matter what clock position the smaller blade is in? If anyone has a picture, this would also help me see how the blades are supposed to overlap each other. |

sorry, I forgot to put the link:

You have pictures on this link.
I do not think that the position matters. |

Thank you for your help! Based on everyone’s feedback, I have successfully put the shutters back together. I also attached a picture with some text to help anyone else out with this arrangement.

Excellent progress. Now you must re-mount the rangefinder shaft before you put the camera back together.
Glancing at the photos of your lens that you posted, it looks as if you have not yet done that. Anyway, here's what this is all about.
If your camera is a Voigtlander Vitessa-T, it's equipped with a Synchro-Compur CN-1110-030 (wide type) shutter, with slight variances between the early and later sub-models of the Vitessa-T.
All the Synchro-Compur 1110-030 shutters have a series of aligned holes drilled in their component parts, through which the rangefinder shaft is axially mounted in the shutter so that it can slide back and forth.
This shaft is about one inch long, and is machined to varying width throughout its length. A thick part near the front keeps it from sliding out of its mounting at one end. At the other end is a tiny coil spring which fits on a threaded part of the shaft; the wider diameter of this little spring keeps the shaft from sliding out toward the front.
The rangefinder shaft is pushed forward from the rear by a spring-loaded part on the shutter mount, which connects the rangefinder system on the camera body to the focus apparatus on the interchangeable lenses.
I know little about how rangefinders or lenses work, so I'm the wrong guy to ask exactly how this shaft functions. But if you dismounted the shutter blades to clean them, you would have had to remove the tightly-wound little coil spring from the back end of this shaft in order to remove the bottom-most of the blades. That's because the shaft runs right through the bushing on which that blade is mounted. With the spring unscrewed, the shaft can be pulled loose from the front and set aside to await re-assembly of the shutter.
And if the fellow who gave you the camera with the shutter in pieces didn't give you that little rangefinder shaft as well, you have a problem.
(Rick, you know a lot more about Synchro-Compur shutters than I do. If my comment on this special feature is incorrect in anyway, feel free to correct me. That's how all of us learn this stuff better.)
