Schmidt roller writer.
Schmidt Rolling Writer System : Fountain Pen parts - NIBS, - Wholesale Fountain Pen Ink - Golden Nib AZ

Just one of the retailers. First one I came to to link, don't rule out others now that you know the name

Richard L. Greenwald sells the section for the Schmidt rolling writer but it has a really strange thread for the section to pen body joint.

I got mine at Exotic Blanks. I think the protective clear cap can be used in a snap cap.
