Blunderbusses are widely recognized for their use by and against boarding parties in naval combat, especially by the British Navy and pirates. This has made them highly desirable collectibles. Those with brass barrels were especially suited for the high seas since they are more resistant to salt water corrosion. They were also used on land for defending coaches against highwaymen. Their flared muzzles acted as a funnel and made reloading much easier while bumping along in a coach or on the rolling seas. It has "London" and a pair of "crown/cross scepter" (no letters) proofs on the barrel at the breech, "Williams" on the lock, a 10 3/4 inch bladed folding "snap bayonet," checkered wrist, and brass furniture with light engraving.
