The barrel is marked Sandwell Minories London. The barrel is also marked with two British proof marks and a maker's mark of a crown over SS. The flat lock with flat gooseneck cock and rounded iron pan is also marked Sandwell, and has a sliding safety to the rear of the hammer. The blunderbuss is adorned with brass furniture that includes a shell form thumb rest, an engraved sideplate, a cupped buttplate with an engraved toe, and trigger guard with floral engravings and an acorn form finial. Walnut stock with brass cap ramrod.
The brass has an even mustard patina throughout. The stock has some nicks and dings, along with an old pin repair to the underside of the butt. There is a small crack extending from the rear of the breach towards the sideplate screw. The bore and mechanics are very good.
