What is it?
A headline typeface built from a Walter Ballmer Olivetti logo exploration drawn sometime in ~1960. Work commenced in 2006 and was soon abandoned. In 2009, work was restarted and completed.
Why the name?
Interno is Italian for internal (according to web translation). A great deal of the classic Olivetti design was down in-house (i.e. internal). Also, the typeface has internal switchbacks reminiscent of a paperclip. Interno sounded like “turning inside” phonetically to me (In-Turn-Oh). Additionally, Interno takes the first letter and last letter of Olivetti and flips it.
