For example, a seven barrel flintlock "volley gun" with one hammer that fired all barrels at the same time. These were used for boarding in naval actions. Four-barrel and seven-barrel revolving flintlock pistols and carbines of pepperbox type with one hammer and rotated by hand. Also heavy brass barrel swivel boat blunderbusses used by the Navy. Under Royal Government contract made flintlock carbines and muskets.
