Hi Everyone, I am sadly in the depths of repair hell so any help would be great. I have no experience with camera repair beyond being a mechanical engineer and mechanism designer. Thus I thought I would be able to tackle this challenge. However I am very stuck. Background: I bought a Minox 35 ML in great condition but the aperture ring would not turn past 4 to get to the other numbers up to 16. I was only able to spin it from P to somewhere between 2.8 and 4. I found a posting on here from 2003 that made it seem very simple, essentially just loosen 3 screws and tighten a few others. How to repair defective aperture on Minox 35 MB? When I loosened the 3 screws, I then removed what I believe is the focus ring and then the next 3 screws (two are large black screws and one is a set screw that is brass) all seemed very tight. At this point I realized that I could hear various things shaking around as if there were loose screws in the aperture ring assembly. I loosened all 3 screws and was able to lift the aperture ring assembly off the rest of the camera. This is where it gets bad. 4 things immediately fell out of the aperture assembly, 1 white plastic piece, 2 tiny black screws and 1 tiny brass cylinder. I don't know where they came from except that they came from the aperture ring assembly. I want to put everything back together but I don't know how I was using the original German repair manual for a diagram but even for me it is too complex to understand. I have uploaded a photo of the relevant diagram but you can download the pdf here: https://learncamerarepair.com/downloads/pdf/Minox-35ML-Repair-Manual.pdf Please help. If you need more photo or details please let me know.
