Looks like a very comfortable finger tip "step" from the section to the threading. This may be important to some users depending on how high they let their fore finger ride on the section or on the threading.
The clip style looks familiar, kind of "Visconti-ish". But, what is important is how is the clip attached and what is the material. Does it have spring and does it grip firmly. Looks very substantial and will take it's work seriously.
I see the cap may be posted by means of barrel reduction. Would the cap post on the first barrel reduction I see or directly onto the end of barrel on the greater reduction? This seems important as it allows a more stable position on end of barrel vrs just a friction fit onto the barrel.
Is that nib steel, white gold or platinum wash over steel/gold? Gold would be nice but silver color seems appropriate for the white structure.
Appears to be full size, comparable to Duofold or slightly smaller Filcao. What is the filling mechanism. Most convenient would be cartridge or cartridge-piston.
I like the red marbled color, has universal appeal but will there be other popular color choices.
Thanks for showing this, great design. Tell us about Galaxy.
