Hamon and nioi line really stand out nicely, as does the hada. Early WWII shin-gunto. Very good condition, well-made. Menuki and tsuba gilded or painted with gilt paint. Same is not special, tsuka-ito is dark brown.
All paint is intact, including gilt paint around edges of metal saya fittings.
All fitting numbers match, including saya liner. The last two characters are in grass-style. After those characters there are two more in pencil.
