I picked this up from my favorite pawn shop in Albuquerque a couple of weeks ago for $400.  After insuring and shipping it to me I have $520 invested in it.  I've had my eye on it for several months and since the opportunity presented itself by traveling there on business I decided to grab it.  They still have a very old flint lock and a "underhammer" that I'm interested in, but that is another day.

This is a model 1816 flintlock musket converted to percussion system using the Belgian Style Alteration and more commonly known as the *Cone Type* conversion. All external lock parts removed with screw holes plugged; the pan ground flush with lock plate (hence leaving remnants intact) and the small existing cavity in pan filled with brass to give it a level or squared off profile along top. The vent hole of barrel plugged with nipple screwed into threaded receptacle at top of barrel, set off center towards lock side; distinctive arsenal, military hammer. (Tom Kelley)

Behind the hammer you can make out from right to left




There should be an eagle and the initials US in front of the hammer, but this looks like it was ground off.  I was told by someone that this was done with a lot of the weapons that were used by the Confederate States of America which were manufactured in the "North" in the "War of Northern Aggression"


Clearly visible on the top of the barrel is the date "1836", a "US" stamp, the initials "J. M." and the letter "P".  I've found no documents that will explain what these represent.



The Model 1816 U.S. Flintlock Musket was produced by both the Springfield (1816-1840) and Harper's Ferry (1816-1844) Armories. During this period, three distinct styles of M1816 developed. The early, or first, style is most often characterized by the use of a stud in front of the trigger guard for mounting of the rear sling swivel, and usually carries an 1817 date on the lock plate. Type II M1816 have browned iron and barrel, have the sling swivel integral to the trigger guard, and usually carry 1822 to 1831 dates. The Type III M1816's have bright finished barrels and furniture (difficult to tell after 175 years!) and are dated 1831 to 1844. The M1816 is distinguished as being the most abundantly produced of all American flintlock muskets, with more than 325,000 produced at Springfield and 350,000 produced at Harper's Ferry. Additionally, more than a dozen contractors also made Model 1816 Muskets during it's production years, adding more than 146,000 muskets for a grand total of 821,421 M1816 Muskets produced.

Model 1816 Musket
From Wikipedia, the free encyclopedia
The US Model 1816 Musket was a .69 caliber musket used in the United States during the early 19th Century.

The Model 1816 musket was originally produced at the Harper's Ferry and Springfield Arsenals between 1816 and 1844, based on the older French design of the Charleville model 1777 musket. Around 675,000 were made in all.

The Model 1816 was at first a flintlock musket, then 300,000 Model 1816 and Model 1822 muskets were converted to percussion cap in 1841. The barrel was 42 inches long, with an overall length of 58¼ inches. A bayonet lug accepted the 19-inch Model 1812 bayonet. With bayonet, the overall length of the weapon was extended to 77½ inches.

The Model 1816 was used by Texians during the Texas Revolution and by the US Army and militia during the Mexican–American War. It was also used during the early years of the American Civil War until around 1862.
