I have a Kaweco Supra that has been inked one time to get a feel, then pretty quickly emptied and cleaned when I realized I didn't like the weight of the brass (or brassy fingers). As far as I can tell, there is no patina (see photos). Everything on the pen is stock, and it has been in a covered storage location for the life of the pen.

Will come with all the original packaging, and an empty standard international cartridge as seen in photos

Asking $75 PP G&S within the continental US.
