@freemo This is my white-whale pen: https://www.penchalet.com/fine_pens/fountain_pens/visconti_leonardo_da_vinci_machina_fountain_pen.html

Hand etched vegetal resin scrimshaw illustration, an excellent power-fill, and an iridium tipped paladium nib, not counting the amazing icosahedron wooden storage box and other fixings...I'm hoping to get it as a present either for finishing my PhD or for getting Tenure/a good paying job, depending on where I decide to go after I wrap up my degree.
