Voigtlander Prominent Lens Disassembly Help!

[Camerakook]

Hi. I just purchased a nice Voigtlander Prominent outfit complete with 3 lenses and many other accessories. The downside is that it stored properly and all three lenses have internal fungus. I want to clean the internal elements but I am having a hard time disassembling the lenses. Lenses are: Nokton 50mm f/1.5, Dynaron 100mm f/4.5 and Skoparon 35mm f/3.5. I started with the Nokton; I removed the front info/retaining ring, but the front element will not come out; I don’t see any other retaining rings. I removed the three screws and ring on the rear mount and can not figure out how to proceed. I can’t find any information online and need some advice. Does anyone have experience with the lenses? Thanks!

It has been many years since I took the Nokton apart. The front section unscrews. Look to see if the front elements unscrew from behind, as they do on the Summarit.

Thank you for the info. I was able to unscrew the front lens group and get to the fungus. Of course I lost the small ball bearing that provides the clicks for the f-stops. Such is life! I’ll have to search for one now.
