Presented for sale here is a vintage Montblanc #6 Lever Filler Fountain Pen.
This pen has the correct #6 nib and Engraving, the nib is semi flexible. Will be a beautiful writer if someone was so inclined. Lever Filler Montblancs are not super common. Most of what you see are Safety pens and Pistons. So this one is quite interesting. The pen does have some fading, but its looks better in person than in the pictures. I really tried to show the fading in the pictures, but the pen is actually quite nice.
There are a few marks on the pen as well including one at the top of the cap as you can see in the picture below. This is a scratch, not a crack.
