Does anyone know how to remove the rear element from the CZ Jena 35mm f2.8 (in praktina mount)? Just purchased one as a 'bargain', the glass is in serious need of cleaning, but otherwise functional. The back element is turning (using a spanner), but not coming off. I got so far as to remove the rear mount itself (very carefully), but I didn't see a way to remove the rear lens group. I plan to use this on my beloved praktina II camera. Thanks!

No, unfortunately. I reassembled, will pick this project up later when I find more information.
