There were three Optima Elite models, the Elite, the Elite 2, and Elite 3. I'm not sure what "Mod. 46" is supposed to indicate, so I'm not sure which Elite model you're asking about.

Based on your description does it look like this?

Ah, now I understand what you're asking about.

Do you have a photo of the Optima in question? I don't recall having ever seen an '70s era Optima with Elite badging and would like to see one. However, to answer your original question, later model Optima portable models (such as the one in my photo in the previous post) were often rebranded Erikas, and that's not surprising given the relationship between all of the East German typewriter manufacturing firms. Optima's focus had shifted toward the production of standard models, by the late '60s it had moved into electro-mechanical machines, and in 1980 the first wave of electronic designs had begun.
