Found in southern Sweden.
Hallmarks (hard to read): a tiny elongated/oval punch that might be the dog head small-article mark, plus a separate small rectangular punch “3”. No Swedish import or cat’s-paw marks observed.
We don’t know the hallmark for sure; based on shapes and the separate “3” we suspect the Austro-Hungarian system, with “3” = .800 and the early practice (1867–1872) of placing fineness in a separate punch. Alternative possibility: the later Hungarian small mark (1937–1966) without an office letter.
Motif (our best read): a floral rosette/spiral “whiplash” head with S-curved shoulders — likely Art Nouveau.
Questions:
– Can anyone confirm A-H small mark + separate “3” (1867–72) vs. the later Hungarian variant (1937–66)?
– Does the motif read as Art Nouveau floral/whiplash to you? Any thoughts on maker/region/date window or close comparables?
