Carl Zeiss Flektogon 35 mm f2.8 (Zebra) M42

My recently purchased Flektogon From a boot sale has fungus. I have cleaned the rear set of elements but can't fathom how to disassemble the front set. Cant find any useful info such as a service manual. Any one have any ideas.

Thanks

If I remember correctly you have to unscrew the name ring, the one with the "Carl Zeiss Jena DDR Flektogon 2,8/35" on it. This is done using a 49 mm rubber tool or other method, being careful not to scratch the front element. After the name ring removal will have access to the rings that keep in place the front elements. A lens spanner is needed to disassembly those.

Thank you very much for that information, I will proceed with great caution.

Thank you again Anthony
