Conklin 75 crescent filler project

Description

Conklin 75 crescent filler for parts.   The pen is not restored and needs work.
There is horrible oxidation.   There is horrible brassing.  The nib and feed need to be refitted into the section.   There are scratches.   There is a mark on the back of the cap that could be a crack or a very deep scratch, see the photo.
I only ship to the US.
