Military terms and nomenclature often overlaps and blurs the situation.
For example, the matchlock muskets were called firelocks, because they held a burning match locked back from the touch hole until ready to shoot by the application of the fire on the end of the match, to the powder. (Well at least that's the version of the origin of the word that I like to use. :wink: )
This is in contrast to the wheel-lock which used a rotating, spring driven wheel against a piece of pyrite to cause sparks that would ignite a gun..., but the wheel-lock was applied to guns while the basic matchlock musket was still being used.
More than a century later, the command words used by the military in combat, plus written in inventories and letters, was firelock, while they meant some sort of firearm that used a flint in the lock instead of a lighted match. For example, Shoulder Your Firelock! was the command as late as 1764 and after.
:idunno:
It wasn't just limited to the 18th century and before...,
In the 19th century, post AWI, the .45-70 cartridge as well as the .44-40, and other such cartridges, the number following the dash was the amount of compressed black powder measured in grains, within the cartridge, BUT when the .30-30 rifle cartridge (aka the .30 WCF) was introduced, the number following the dash was the amount of modern, nitro cellulous based powder measured in grains that was within the cartridge.
So today, we have a very blurred definition.
In Maryland for example, according to the colony records that survived from the 18th century, there are "old muskets" and "new muskets" at the time of the F&I War. Prior to that they also use "fuse" and "carabines". The general idea one gets from those records from the 18th century just prior to the F&I, is that a "musket" to these folks mounted a bayonet, BUT what made some "old"? Was it age? Were the old muskets of Dutch pattern, while "new" were of English pattern? Was it condition, old muskets being rusty and non-working vs. new muskets being ready to go to war? Were the old muskets using dog-locks, while the new muskets had the more modern flintlocks though perhaps being decades old British Army surplus?
It's bloody frustrating, not to mention nobody mentions if any of these are French, Dutch, Spanish, or British in appearance.
GAD!
