This is a NEAR FINE condition example of the .69 caliber socket bayonet known to collectors as the US M1842 Socket Bayonet. The designation as the M1842 is only a modern term of convenience used by collectors, and this designation was never applied to this pattern of bayonet. The reality is that this pattern of socket bayonet was not even produced until after 1855. The more correct term would be the US M1835/40 “Replacement” Bayonet. These bayonets were produced after the adoption of the US M1855 socket bayonet and were intended to replace those earlier M1835/40 socket bayonets that had been lost or damaged in service. The bayonets utilized the original pattern M1835/40 .69 socket, mortised for a bottom mounted lug, in conjunction with the then current pattern M1855 bayonet blade. This made perfect sense as all of the bayonet making machinery had been changed over to manufacture the M1855 .58 socket bayonet. This also allowed both the current issue M1855 bayonets and the M1835/40 replacement bayonets to use the same pattern bayonet scabbard, the Pattern 1857 as well as the later Patterns of 1863 and 1864.


This .69 caliber US M1835/40 Replacement Bayonet is in very nice condition. The ricasso of the blade is clearly and crisply marked with the typical U.S. stamping, although the stamp is struck at a slight angle. The rear edge of the socket is stamped with a  small capital C inspection mark. The blade of the bayonet is full length and the original locking ring is present on the socket and remains fully functional. The blade has a mostly bright steel appearance and was probably lightly cleaned at some point in time. There are some areas of duller gray patina, as well as some flecks and freckles lightly oxidized age discoloration. The metal is almost entirely smooth with no surface roughness or pitting. The socket shows a similar steel gray color with scattered light surface oxidation as well. There are some scattered minor impact marks and tiny dings along the edges of the blade. The socket and neck of the bayonet also show a few minor impact marks, typical of bayonets that saw any amount of actual service and use.


Overall this is an extremely nice example of the Civil War era .69 caliber socket bayonet for the US M1835/40 and M1842 muskets. Although the collector name of M1842 is technically incorrect, it is not likely that the designation will ever be replaced in the collecting community. This is a solid bayonet to add to your higher condition US M1835/40 conversion musket or your M1842 musket, and would be a very nice, high condition addition to any Civil War bayonet collection. These bayonets also typically fit the Armi-Sport reproduction US M1842 Muskets, so it would be a good candidate for living history use as well.
