Fabriano's own paper-mill archive (Fondazione Fedrigoni) dates its earliest surviving watermarked papers to 1293, not 1282

The Fondazione Fedrigoni Fabriano holds the Miliani Paper Mills Historical Archive in Fabriano itself, including the Zonghi collections assembled by 19th-century Fabriano watermark scholars Aurelio and Augusto Zonghi, themselves collaborators of Briquet. The foundation's own description of its primary holdings states that its watermarked Fabriano papers span 1267–1798, but that "the first watermarks date back to 1293." A second, related Zonghi-derived collection in the same archive is separately described as papers "dated and manufactured in Fabriano between 1293 and 1599."

Both figures — describing the institution's own surviving physical material rather than a secondary retelling — place the earliest confirmed Fabriano watermark eleven years later than the popularized "1282." This is an independent line from the Briquet-catalog uncertainty discussed in claim-briquet-entry-5410-earliest-watermark-question-mark-and-bologna-provenance: it comes from Fabriano's own archive, not from Briquet's Bologna-sourced entry, and it converges on a different but similarly non-1282 answer.
