I have never seen, or heard of (until now) a Rodenstock lens bearing the APO Artar name. It would be most unusual since first Goerz and then Schneider held the legal rights to this name - and they were both competitors of Rodenstock. Rodenstock had their own version of this lens type, but they called it the APO Ronar. Are you sure that's not what you have?
