Are these two pens among of the many versions of the Ogiva? The only barrel imprint is these three words in a row: "Omas Extra Italy." I'm not at all well informed about Omas pens, but I was guessing the 1980's, give or take, and that these are pretty low end, as far as Omas pens go. Anyone know anything about them, like what the material is, or what they might be worth paying for nowadays to use as knock around (to and from the office) writers? Some of you are bound to know, but I'd appreciate even a somewhat informed guess.
