So I know it does exist. If you recall, Didier qualified his remark with "older" or "earlier" lenses. All of my KMZ lenses, with the one exception of the Jupiter-8, follow the convention of using the year as the first two numbers (I have more lenses than I really want to admit). It seems it is a convention they introduced around the 80'ies, like you say.
