The Musket is a type of firearm that typically featured a long, smoothbore barrel and fired either a musket ball or (from the 1840's) a Minie ball. The Musket was heavily developed during its 4 centuries of use from the 1400's to the late 1800's, with different types of muskets evolving.
There were revolver-type guns that date back to the the 1500's, but are not true revolvers. Elisha Collier invented the first true revolver in any widespread production, 18 years before Samuel Colt saw Collier's inventions while serving as a cabin boy, and came up with his own design. Colt's design was the first widely adopted modern caplock revolver, the Colt Paterson; but he was not the inventor.
