This is a VERY GOOD+ condition example of the US M1835/40 socket bayonet. The US M1835/40 socket bayonet was the first US socket bayonet to incorporate a locking ring to ensure that it remained firmly attached to the gun it was fixed upon. The bayonet was an almost direct copy of the French M1822 socket bayonet. The bayonet was designed for what would be the last of the US flintlock muskets, the M1835/40 and continued in use through the production run of the first US percussion musket with interchangeable parts, the M1842. The M1835/40 bayonet remained in production until the end of M1842 musket production in 1855. The bayonet featured an 18” blade, with the squared off shoulders that were typical of the earlier 1816/22/27 series of socket bayonets. The socket was mortised for a bottom stud and was sized for US .69 musket barrels.
This bayonet has a clear and deep US stamp on the face. The locking ring is complete and fully functional, and the blade is full length. The bayonet has been cleaned to bright. The blade has a mostly smooth bright steel patina with scattered oxidized freckling and minor age discoloration along the entire blade, giving some portions of it a mottled appearance. The blade shows some small areas peppering, pinpricking and light pitting. The most noticeable area of pitting is in the last 3”-4” near the tip. The socket has nearly the same coloration and bright steel patina as the blade. The socket shows some lightly scattered surface oxidation and minor pinpricking as well, matching the blade quite well. The entire bayonet is in very nice, fairly crisp condition. It would be a great addition to your US M1835/40 or US M1842 musket. For the re-enactor or living historian, these M1835/40 bayonets almost always fit on the reproduction Armi-Sport M1842 muskets, as well as the original muskets.
