Very, very nice pre-owned Montblanc Meisterstuck 4810 No. 146 14K 585 Black & Gold Fountain Pen. Believe the vintage to be from the 1980s. I am not 100% certain that this is a broad nib as there are no nib size markings, but it does have some thickness to it when writing. Could potentially be a medium, but it seems too thick to me.
