The Montblanc Meisterstück 121 was produced from 1970 to 1973/74 with thick feed and from 1974 to 1979 with flat feed; a dating to the 1960s therefore does not quite fit. It is an original and not a counterfeit; no plagiarisms of this model are known. The collector value is rather low, because the model is still too young for a pronounced collector demand. As a reliable daily writer, the 121 is, however, still usable.
