This is a Montblanc Classique Meisterstuck Fountain Pen in the Bordeaux (Burgundy) color with Gold trimmings. I believe the nib is a medium and it is 14k gold. The pen measures 5 3/8 in length with cap on. The clip reads "Meisterstuck" but there is no serial number making me think that it is pre-1990s. No converter and there is a small inkspot on satin interior of the box (see photos).
