I love my Indian ED but I also like to use a cart or a converter when I am at work.
This one has a really nice shape to it and a really rugged pen that I love having at work with me so I thought I would convert it over.
After looking at the section I thought I might as well just make up a new one as I was not sure I could drill and thread the old section.
I had some left over ebonite form a pen a bit ago so I made up a new section with a Schmidt nib in it.
It will take the long Waterman cartridge or a converter.
