The writing instrument corresponds to the Montblanc Noblesse 1128, which was made from 1976 to 1980. It is a comparatively low-priced model of that time; the last shop price was around 98 DM, before that around 120 to 125 DM. Owing to the high production numbers, the collector value has not significantly increased today. A 585 hallmark on the nib confirms the gold material of the nib tip.
