This is a VERY GOOD+ condition example of a later production US Model 1816 Socket Bayonet. While the term “1816” Bayonet has been a collector’s term of convenience for many years, only the earliest production bayonets from the series were actually “1816” bayonets. More accurately the later production bayonets of this basic pattern were designated as the Model 1822 and Model 1827. The Pattern 1827 was simply an improved and substantially more standardized version of the earlier Pattern 1822. In 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 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 .52”, substantially larger than the previous maximum neck dimension of .450”. The bayonet has a full-length blade, measuring 15 7/8” in length; well within the tolerances of the nominal standard of 16”. 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 larger than usual, measuring .850”, which should allow the bayonet to fit on a wider range of muskets and even earlier M1816 (Type I) and M1822 (Type II) muskets. This suggests that the bayonet may be one of the “replacement” M1827 pattern bayonets, intended to fit on those earlier guns with more irregular bore diameters. The nominal bore diameter for most M1816/22/27 pattern socket bayonets was .830”.

 

As noted, the bayonet is in VERY GOOD+ condition and were it not for some pitting on the socket would rate about fine. The face of the blade is clearly marked US / TA and with a hardness test punch dot at the shank to blade junction. The “TA” mark is that of Springfield Arsenal bayonet forger Timothy Allen. The rear edge of the socket is marked with a pair of hash marks and a pair of punch dots that were likely manufacturing or possibly mating marks. The metal of the bayonet has a relatively even pewter gray patina, with some scattered flecks of surface oxidation and minor age discoloration here and there. The blade is essentially free of any pitting, although there is a small amount of pinpricking on the face of the blade and slightly more on the reverse of the blade. The socket shows more surface oxidation and discoloration than the blade, as well as some scattered light pitting. The lower left side of the socket is where the largest amount of this minor pitting and freckled discoloration is located.

 

This would be a very nice addition to the display of a higher condition US M1816/22/27 Musket and would be a quality addition to any early 19th century US socket bayonet collection. The bayonet is a solid example that I’m sure you will be glad to add to your collection.
