By chance I stubmled on this Olivetti ETP 92 in a thrift store, got it for 10€. Now I need some help, as far as I can tell this typewriter is functionally the same as the Olivetti ETP 55, from pictures and descriptions. But I can't really find any information about the ETP 92. Is it some regional naming or is it an oddity or just so not interesting enough to have much information online? Any one here know anything about this novel machine. It works perfectly and I have replacement ribbons on the way already, hopefully they fit.
