Gillette Argentina is a plant with no dating record at all. The collector wiki node for Argentinean dating information does not exist — the page returns a soft not-found inside a 200 response — and no local canonical table was found in English, Spanish or Portuguese.
The dating page that the collector wiki would hold does not exist, and the search covered English, Spanish and Portuguese material: the wiki node, the official Latin American site, and the forum threads that are all that remains.
Not from the marks. This plant has no serial table and no date-code table in any source that was checked, in English, Spanish or Portuguese, so the archive returns no year rather than borrowing one from the American line. Dating it would mean building the evidence from photographs of the stamps, cases and blades.
