Here is a NEAR FINE condition example of the US M1816 Socket Bayonet. The term 1816 Bayonet” has long been a collector’s term of convenience, however the more accurate designation for this particular pattern of bayonet is the Pattern 1822 Socket Bayonet, and subsequently the Pattern 1822/27 or 1827 Socket Bayonet. The Pattern 1827 was simply an improved and substantially more standardized version of the earlier Pattern 1822, which was itself a more standardized and improved version of the earlier Pattern of 1816 socket bayonet. By 1827, Colonel Bomford of the Ordnance Department has ordered that a more standardized version of the current pattern bayonet be established to increase the interchangeability of bayonets with the muskets. This was particularly important for contractor-produced bayonets, which tended to have dimensions that varied more than the bayonets produced by the National Armories. The primary feature that can be easily noted to determine is a bayonet is of the Pattern of 1822 or Pattern of 1827 is that the latter bayonet has a minimum neck dimension that is greater than .450” where the shank meets the blade. In the case of this bayonet, that measurement is .50”, indicating it is a post-1827 production bayonet. 

 

The bayonet offered here is an interesting example of just such a post-1827 produced bayonet.  We know it was produced after 1827 due to the fact that the minimum neck dimension is .50”, larger than the previous maximum neck dimension of .450”. The bayonet has a full-length blade, measuring 15 7/8” in length, which is nominally 16” and well within the tolerances of the era. The blade has a prow-point tip and an 85/8” face flute. The overall length of the bayonet is 19”. The friction-fit socket is the usual 3” in length, with the standard Wilson’s Patent improvement “T” shaped mortise that was introduced in 1816. The bore diameter is the expected nominal bore diameter for most M1816/22/27 pattern socket bayonets at .830”. 

 

The bayonet is in NEAR FINE condition, with the metal remaining mostly smooth and showing some lightly scattered flecks and patches of oxidized discoloration on the metal, which has a mostly medium dull pewter gray patina. There is a thumb-sized patch of light surface rust on the rear obverse edge of the socket, which could be cleaned if so desired. There appear to be some traces of the original arsenal brown finish here and there on the bayonet. The minutes traces of finish are thin and streaky. We can tell from the markings that this bayonet was produced during the end of the “National Armory Brown” period. As is typical of any socket bayonet that saw actual use, the bayonet shows some scattered minor impact marks, primarily on the bayonet’s neck and on the socket. The face of the blade is stamped US / SM at the ricasso. The “SM” is the mark of the Springfield Manufacturing Company, a Springfield Arsenal sub-contractor located in Springfield, MA. The firm was established not long after the armory was built and served to provide a variety of metal products for the production of small arms. Over the years, the Springfield Manufacturing company produced not only socket bayonets but ramrods, barrels and a variety of small work and gun furniture. We can date this particular socket bayonet to the period between 1829 and 1831, as the earlier version of the Springfield Manufacturing Company mark was SM / Co. The “US” is deeply struck, as is the “M” of the two line marking, while the “S” is light, suggesting an uneven strike with the “SM” die. The arsenal applied serial number mating mark A / e 93 is stamped into the right side of the socket forward of the mortise cut. This mark would match the same mark on the breech of a Springfield Arsenal produced M1816/22/28 musket.

 

Overall, this is a very nice, crisp solid example of a later production US M1827 socket bayonet with great arsenal marking marks that was produced during the M1822 (US M1816 Type II) “National Armory Brown” period, which would be a very nice addition to your late production US M1816 Type II (M1822) Springfield Musket.
