Zeiss Contessa - Cleaning/Servicing

I've an old, very old Contessa, probably dating from the 1960's and while it is still working I noticed that the photos appear a little hazy.

On closer examination it looks like the lens (inside and out) is dirty. This could be just dirt or I'm afraid it could be fungus.

I'm looking for recommendations of where/who I can get to look at the camera and offer suggestions.

Any help/suggestions would be gratefully received.

Sal.
