One can reach a much higher level of precision by hand than most people understand. As an example people who hand grind telescope mirrors for reflecting telescopes. It is possible to produce very flat surfaces by hand using The Three Plate Method in which three flat surface plates are produced using two plates to check the third and alternating which plate you are scraping by hand. Scraping is an art all in itself. The trick is of course developing the set of standards and measuring tools required for two individuals in different locations to produced parts within tolerance that will work together. Some would say the development of the first screw cutting lathe really jump started the Industrial Age. Some would say the steam engine. In reality it was a number things working together.

Two key developments in the ability of the ability to produce tight tolerance work on a mass scale was the development of the first commercial micrometers (Palmer in France and Brown and Sharpe in the US) and gage blocks by Johannson in Sweden. These combined with flat surfaces allowed the inspection levels required. Moores Foundations of Mechanical Accuracy covers a lot of what is really required.

Probably boxes of 5 colors. Red, Blue, Yellow, Black and White. Crayon is of course pencil in French Techniques for wax colored drawings go back to at least the 1st Century AD.

@Deridus All it would really take is either an oral description or a general drawing for the starting point for the development of the Kammerlader. But who knows. It is entirely possible that one or two of Hall's commercial guns made it to Norway sometime prior to 1840.

@itatane With Pvt Mackenzie from British Muzzleloaders being the Scottish branch of the clan. Bloke travelled to Alberta or BC to do a series of videos with him. One thing I enjoy about British Muzzleloaders is his historical approach not only to the particular firearm but also the context of its usage in both field exercises and training.

Americans tend to associate the word 'crayon' with the wax based crayons used by children in school or coloring books. In other countries the word is often associated with pencils too. In Europe what we called color pencils are sometimes referred to as crayons. I'm not sure but I think the crayons used by lithographers* are primarily oil based and are a whole different ball game than Crayolas *Traditional lithography involves drawing the scene in reverse on a porous stone (hence the litho) surface and then pressing the the paper under high pressure to transfer the image. A lot of the Currier and Ives prints were lithographs. The down side is you can only get a limited number of prints before the master image either needs to be refreshed or the surface prepped for a new image.

The Blackhack war was primarily in the Wisconsin Territory. One of the principle US Army officers involved was John Anderson who would later command Fort Sumter. At the time Wisconsin was also spelled Ouisconsin.

"We gave you a contract to make rifles. Where are they?" "Frist you need the tools to make the parts and then you need the tools to make the tools to check the parts." I really think Hall was a if not the true originator of mass produced items he was one of the first. One of the first mass produced items that I now of was the blocks used for handling lines on ships for the Royal Navy. The RN set-up a factory to mass produce block and tackle in Portsmouth iirc. But in terms of looking at manufacturing as a system to produce items industrially I think Maudsley in the UK gets the nod. One more item. The first standard screw sizes in the US originated in the Civil War. Machine tool manufacturers used to be notorious for using their own thread size and pitch combinations. Brown and Sharpe was one of them. It's called "buy our parts".
