I purchased this pen new in the late eighties, perhaps early nineties. It uses a cartridge and is 139mm long capped, 120mm long uncapped, 12mm at its widest point. The only marking on the nib is "Mont Blanc". The nib is golden, though it may not be gold, maybe plated. The pen is very light, the nib is either fine or extra fine. It is not a very good writer, quite scratchy and somewhat dry.
