The lock has a catch or dog at the rear in addition to a secure half-cock notch. Though doglocks were largely supplanted by "true" flintlocks by the late 17th century, a dog catch remained a more secure way to carry a loaded weapon than simply relying on a half-cock notch, and they remained in use into the first quarter of the 18th century. Based on the plate on the left side of the forend, it appears this blunderbuss once had a sling bar and ring mount which would have made it easier to carry for a mounted combatant. The muzzle measures approximately 1 1/8 inch tall by 1 3/4 inches wide (gauge estimated) which allows the weapon to have some of the easier reloading benefits of a bell shaped blunderbuss while also preventing the muzzle from obscuring a proper sight picture. In fact, while most blunderbusses have no sights, this one has a brass blade front sight. The only visible markings are a faded mark on top at the breech end of the barrel, a "2" on the stock to the left of the trigger, and an "R" over an "X" cartouche to the rear of the trigger guard tang. The metal components are all iron, including the ramrod.

Fine with mostly gray and brown patina, some minor pitting, replaced top jaw and jaw screw, a few minor cracks and tiny worm holes in the otherwise very good stock, some well-executed repairs in the forend, and general mild dings and scratches. Mechanically fine.
