I had a couple sections floating around, a Cross and a Pilot. With a bit more vintage material I had on hand decided to make up a body to hold them both.
This material is made by wrapping it around a rod so you have to deal with working a tube material. It is a bit hard to see but the end is a tortoise material and when it is held up to the light it is transparent.
So depending on my mood I have a choice of two nibs to use.
I once again used a Here slip on cap.
I am almost through my stash of caps honest.
