I have only one lens with that convention, starting with zero, a
rather late Jupiter-8. 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.
