I am positive there is many, many more (especially of the art techniques), however because of tags playing up and my blog had a problem with a whole page disappearing, these are the only I could find at the moment. More will certainly be added. You can exoect another post filled with even more art history info! Hopefully all the links work.
Manufactured by Henry Nock’s company in London c.~1800 - no serial number. .44 ball, smoothbore manually indexed six-barrel cluster, self-priming flintlock. A considerable upgrade on his 1779 seven-barreled volley gun, Nocks uses the revolving technology of American gunsmith Artemus Wheeler and adds to it a self-priming mechanism of his own design, which would later be the basis of Elisha Collier’s famous designs. This firearm would allow its user to fire a shot, lock the barrel cluster into its next position, cock the hammer, lower the frizzen and take another shot, up to six times in a row. It was a considerably faster rate of fire than any musket at the time.
Manufactured by Diwisch in Brno, modern-day Czech Republic c.1800~1830 century. 38cm long, dual set trigger, steel bow and octagonal barrel. A very elegant weapon, probably used for plinking before the age of Flobert guns.
