Hello, if anyone can help me, how can I properly clean a Voigtar f/6.3 lens from a 1930 Voigtländer Bessa 6x9 camera? The lenses are very dirty and probably also have fungus. Attached I am sending some photos of the camera and a few pictures taken with it so you can see its condition and whether anything can still be done.
One of the photos is sharp on the right side, while the left side is not as sharp, and I don’t know if this is caused by the dirty lens or because the lens is not parallel to the film plane.
Thank you.
