Hi everybody from Istanbul, I have been following this wonderful forum for months and waited to write a message up to day because I need your help. I won a bid at ebay and bought a Delta Dolcevita Federico Media Oro Fountain Pen with Fusion Nib from Martemodena_Europe. I think most of you are familiar with martemodena. My pen is not "Stantuffo" but "Media". I asked Giulio from Martemodena the difference between two models and thanks to him he replied very fast with below answer: "Regarding the Stantuffo has the real piston filler and the ink ispection window, and regarding Media it is ink converter which can be used as piston filler as well" As far as I know Stantuffo models are also ink converter which can be used as piston, am I wrong? So my question is that, is there any friend here who has Dolcevita Federico Media model pen and can you send me some pictures, especially about the filling mechanism? Thanks in advance for the replies.
