Hello, I have recently received my grandfathers fountain pen and a mechanical pencil. I'm more interested in the pen. I know its a Montblanc and it was made in West Germany. It says M/14ct on the little sticker and 14K 585 on the nib. I've done some googling and looked on the website but haven't found any matches, i believe it's a bit dated.. Any tips on what the model or history is would be greatly appreciated! I know nothing of pens but since the aquisition of this piece I am very interested!
