The 161 with the characteristic pointed ring (form of a mountain as the symbol of the Montblanc) was produced from 1971 to 1973 and corresponds visually to the 151. The 6 in the model number identifies the Meisterstück range and means that 1.18 mm leads are used. In quality, the Meisterstück pencils and ballpoints of the second and third series of the 1960s and 1970s differed mainly through different surface versions; alongside stood the simpler mass models like Noblesse, Monte Rosa, Carrera and Caressa.
