The cap is black and the band is green. Very nice on that pen is the clear transparent section.The pen will be produced in the 1940ties. You can see that on the piston system. 1942 the cork seal on the piston head is replaced by an elastic synthetic material and this pen has got the late version piston system. The nib of the fountain pen is a 14 Karat nib in size F. Often these 100N models have broken caps or the cap bands are loose, but this pen is without this problems. The filling system works smooth and perfect. A real nice pen for a collection or to write with. The item "Pelikan 100 N fountain pen green 1940ties F nib #" is in sale since Tuesday, October 8, 2019.
