I have this bronze arco Paragon, 141 or 142 mm, BB nib, with no year stamped on the section (or anywhere else I can find) It has a black box (no ink) with a black booklet and black paper outer box. I'm curious about it's age, and know next to nothing about Omas. I have another identical pen (B nib) dated 1998 on the section, with an off white box that says "Collezione Celluloide" on the tray (no ink) with a tan booklet and tan paper outer box. Please, can you help me with the unmarked pen? And do I have the boxes mixed up? After looking through the threads I'm wondering if there was an undated old style model in the early LVMH years.
