Montblanc Vintage No. 256 Black Resin Fountain Pen
This is a vintage fountain pen that has seen regular use and shows signs of having been lovingly owned through the years. There are some small scratches on the body and cap with a significant scratch on the piston, under the nib grade designation (see last image). It is equipped with a marked 14C KM (Kugel Medium) Wing Nib which has been ground to a Smooth, responsive Stub and fills via a piston filling system. (Writing Sample at the bottom)
