This bayonet was designed to fit the Modelo Argentino 1909 Mauser Infantry Rifle, manufactured in Germany under contract. Most of these bayonets - if not all - were manufactured by Weyersberg, Kirschbaum, and Co. (company). They are extremely well made and are usually found in very-good to excellent condition. They are found with wood grips, steel crossguard, and hooked blade-breaker quillon. The latching mechanism is of the push-button/internal-spring type. The blades are straight, single-edged, and fullered on both sides. The blades are usually stamped - on the ricasso - with Weyersberg, Kirschbaum & Co / Solingen on one side, while on the other is the Argentine Crest (this is usually ground off when released from the arsenal as surplus wares) and Modelo Argentino 1909.The scabbards are of sheet-rolled steel, ball finial, and are usually dark blued finish (almost black).Both bayonet and scabbard are stamped with a serial number, beginning with an alpha-character prefix, followed by a 4-digit number. It is desired by collectors that both bayonet and scabbard numbers match, otherwise they are considered mis-matched.
