4.0 What are the parts of a fountain pen?

The pen has several components which make up two main systems: the body, and the ink path. The body usually consists of the barrel, the section (the thing that the nib is mounted on/in), and the cap. The ink path consists of the ink reservoir and filling mechanism, the feed (the non-metallic thing the nib seems to be sitting on), and the nib itself.
