From my notes. Maybe it's useful to someone. Not comprehensive as there are other brands and other iterations I'm sure. Many dpreview.com sample galleries show original filenames. Some forums list filenames, youtube descriptions can list model names, pdf manuals and manufacturer websites sometimes list the names. There isn't really a good list of these that I know of.
