That's an outstandingly beautiful pen !! The pansies look so natural .... Marla sure does make gorgeous blanks.
The Napoleon kit is one of my favorites, especially the black titanium one that you show. This is a barrel twist.
Have you tried the similar kit that Smitty sells ? I think he calls it the Le Roi Elegant Major, and I think it has a finial twist instead of barrel twist, and the plating options might be different. If you have tried it I'd like to know how it compares to Napoleon ??
