Cascabel (artillery)

Drawing of breech of cannon. A=knob, B=neck, C=filet, D=base of breech.

The cascabel is the portion of a muzzle-loading gun consisting of the knob, the neck, the filet (if present), and the base of the breech. However, frequently the term is used to refer to just the knob, neck, and filet (if present). The cascabel has several forms in addition to the one illstrated.
