French Model 1866 "Chassepot" Yataghan Sword Bayonet

Description

Information obtained from website below: The classic French bayonet, the fifth in the Yataghan series of bayonets. Lighter than the original 1840 bayonet that started the family, the bayonet has the same brass hilt and double curved yataghan blade. Manufactured from 1866 until some time after the introduction of the 1874 Gras, the blade remained in service until around 1900 in ceremonial usage. The history of the Chassepot is somewhat confused due to three changes in the markings applied to the bayonet as production started in the 2nd empire period, continued through the Franco Prussian war Defense Nationale government and on into the 3rd Republic. In addition the blade was manufactured by several foreign suppliers during the FP war - including German manufacturers.
