This is an old-stock Visconti 14ct gold nib in the smaller size for older REmbrandt, Van Gogh, Michalangelo, etc. pens. The bronze finish on this nib is very unusual and was produced for the original model Michelangelo pen, and as far as I am aware, was never used on any other pen. The 14ct gold nibs are now being made again by Visconti, but not in the bronze finish, so I am selling off the last of my stock of these. I have tested each nib to make sure it writes well, so you may see some ink residue on or in it - this is just from testing. It has not been used otherwise.
