Delta Limited Edition Colosseum / Colossevm Fountain Pen 18K Nib NOS
18K medium nib

This iconic Delta has ver seen any ink. Beautiful and classic. The pen is like the famed Docle Vita. But in my opinion this one is more comfortable to use. Longer barrel and perfect grip section.

The lever filler works but you may need to replace the sac as it is likely ossified due to age.
