Here is a VERY GOOD condition example of the US M1816 Socket Bayonet. While the term 1816 Bayonet has been a collector’s term of convenience for many years, the more accurate designation for this style of bayonet is the Pattern 1822 Socket Bayonet, and subsequently the Pattern 1827 Socket Bayonet. The Pattern 1827 was simply an improved and substantially more standardized version of the earlier Pattern 1822. By 1827, by order of Colonel Bomford of the Ordnance Department, a more standardized version of the current pattern bayonet was 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”.

 

The bayonet offered here is a very nice 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 .51”, larger than the previous maximum neck dimension of .450”. The bayonet has a full-length blade, measuring 15 15/16” in length. The blade has a prow-point tip and a 9” face flute. The friction-fit socket is the usual 3” in length, with the standard “T” shaped mortise. The bore diameter is a little tighter than usual, measuring .820”, about .01” smaller than normal. The nominal bore diameter for most M1816/22/27 pattern socket bayonets was .830”. The socket may be slightly out of round, which would explain the tighter than normal socket measurement. 

 

The bayonet is in VERY GOOD condition, with the metal remaining mostly smooth and showing a lightly oxidized brown patina over most of the metal with scattered areas of more deeply discolored patina producing a somewhat mottled appearance. There is scattered surface oxidation and age discoloration present on the bayonet, most notably on the rear of the blade, along with some scattered minor roughness as well. There are also traces of old black paint here and there on the bayonet. The bayonet also shows some lightly scattered impact marks, primarily on the bayonet’s neck and on the socket. The face of the blade is deeply stamped US / SE at the ricasso. While Peter Schmidt’s U.S. Flintlock Military Muskets & Their Bayonets – The Later Years 1816-Civil War lists the initials “SE” as being those of a bayonet contractor, he does not indicate to whom they actually belong.

 

Overall, this is a solid example of a later production US M1827 (M1816 Type III) socket bayonet with a clear blade mark and a slightly tighter socket than normal for a US M1827 socket bayonet.
