Even though the Montblanc Meisterstück Fineliner was introduced as something of a small revolution, Finelliners from Montblanc existed before. Today two variants of the original Fineliner refills are in circulation: the older variant and the current version. Both fit the older as well as the new writing instruments. In addition there was another variant from roughly 1972 to 1990, namely the older version without thread, intended for the Montblanc Quickpen and similar models.
