Leica used several sources as suppliers for speciality (shifts, superwides) as well as entry-point optics. Schneider-Kreuznach, Minolta and Sigma were or are among them. Currently the 4/80-200mm is manufatured by Kyocera who also manufacture most (but not all) lenses for the Contax-SLR. This lens was nevertheless developed by Leica and is not available from any other source. With respect to the different incarnations of the 50/1,4 I suggest you visit the forum at http://www.leica-camera.com/. But better wear your flamsuit before you suggest that it is or was made by Zeiss.
