Japanese omi no yari signed Norimitsu spear from the late 18th and early 19th centuries

Construction of the yari - hira sankaku blade. There are minor scratches, delaminations, bumps and curvatures on the blade associated with the passage of time and the fact that this weapon was used on the battlefield. Overall condition is good. Estimated time of manufacture is the late 18th and early 19th centuries, or the Edo period. Norimitsu's signature is preserved on the nakago. The tachibashiri (the part of the spar securing the blade shaft with bushings and rings) and saya probably made at a later time or restored. Gyakuwa (sleeve), dogane (rings) and hirumaki (spar end) made of brass. A virtually identical blade was presented and described in Wieslaw Winkler's book "Japanese Spar Weapons" and is now in the Polish Army Museum. Overall length : 252.3 cm. Blade length : 41.5 cm. Dating : late 18th and early 19th century
