William Kavanagh was active in Dublin from 1816 to 1849. His sons continued on the business, and it remained open until 1923. He was one of the best Irish gunmakers. The barrel has an oval (elliptical) muzzle that measures 1 3/16 by 1 7/8 inches, a roughly 12 gauge bore, girdled transition, "Kavanagh Dublin" on top in script, a folding "snap" bayonet offset to the left, and an engraved breech plug and upper tang. The lock has floral and scroll engraving and is signed "KAVANAGH" near the center. The other fittings also have some light engraving.

Fair with mottled gray and brown patina throughout, extensive mild pitting overall, bent bayonet blade, mostly crisp checkering on the wrist, some small chips, general scrapes and dings, and a repair at the heel. It is mechanically fine.
