it looks like the disassembled pen has an ink cartridge, instead of dipping the pen in an ink well?
just curious.
That pen has a "converter" piston pump for a reservoir, for use with bottled ink. Almost certainly, you can pull the converter off and put an ink cartridge on in its place to use cartridge ink rather than bottled ink.
Kit pens usually come with a converter and an ink cartridge. The ink in the cartridge is not very good, so if you are going to use cartridges, it's better to get some good cartridges.
By the way, a "dip pen" is an older style of pen than fountain pens. That's what you would dip in an ink well. It's basically just a nib and a holder for the nib, and you keep dipping as you write because the nib dosen't hold much ink. A fountain pen has a reservoir to hold a supply of ink, so you don't have to dip it.
