| Notes | The caliver was an evolutionary step in the matchlock, evolving from the arquebus. The caliver introduced standardized bore sizes and some replaced trigger levers with the a trigger more recognizable on modern firearms. Unfortunately, the trigger cannot be seen in the image. |
Caliuers / calieuers – Each of these variants of “calivers” occurs in a different portion of the text, the first in Hariot in reference to a hunt, and the second in Lane as part of a list of weapons. The OED defines a caliver as a light harquebus or musket and the lightest personal firearm (besides a pistol), able to be fired without a “rest” for the muzzle. - Matt
