I have received my Modello 60 from Robert Dubois, who is great gentelman and I highly recomend him.
Tibaldi Modello 60 is big pen. Abount 1cm longer than Omas Paragon or Parker Duofold and about same diameter as Duofold.

One thing that is striking on Modello 60 is celluloid. It is gorgeous. Pictures on internet don't do justice to it. It looks like dark green / light green combination. But in fact, there is beatifull blue cobalt colour that sometimes looks cobalt blue and sometimes dark green. It really depens on angle. Second colour is gorgeous pearl ivory colour that goes to dark vanila. Ivory part is shiny. On pictures you may get feeling regarding deepness and shine pearl effect.

I got Extra Fine nib that is probably between extra fine and fine. For EF nib, it is very smooth. Very nice nib. Not a flexy, not soft, but neither firm. Just right.
Pen is piston filler. It takes tons of ink. Celluloid is translucent, so I am trying to stay away from PR and Noodler inks. Whichever ink I take, it writes without any problem.
Flow is good. Even with fast writting, for example taking notes at University, there are no problems.

As of value, this pen used to retail for 850 euro's. I don't thing that is worth that kind of money. But at current eBay prices, it is a steal.
