Comparison between Pelikan 140 (c. 1960) and Pelikan M400 (c. 2010), both green-striped.
The color of the 140 has faded from age and sun exposure, but you can see that near the section, there is about a centimeter of stripe that would usually be under the cap and wouldn't be exposed to direct sunlight. So the color there is actually much closer to the modern M400.
