That is a truly beautiful pen, Mark !!! . Well done, and Congratulations !!!!!
It is another Executive, which you seem to like a lot; and I never cease to be amazed how successful you seem to be with the Executive give the facts that the blank-end material is so thin, and that your chevron blanks are quite fragile (I would think, anyway).
I realize that the solid end rings in your design help to alleviate this potential problem.
EDIT: The No-Press version of this kit exaggerates the problem because the brass tube with threads is thicker than the original brass. . I have not actually tried the No-Press Executive, but I have made several of the No-Press Diva Charm kits and what I said is true for them.
