Our Assessment: Joseph Manton was a British gunsmith who innovated sport shooting, improved weapon quality and paved the way for the modern artillery shell. Manton was a sport shooter in his own right and a friend of Colonel Peter Hawker. From 1781 onwards, he produced about 100 weapons annually, including dueling pistols and shotguns. In the early 19th Century, he invented the tube or pill lock, an improvement over Alexander Forsyth’s scent-bottle lock, but although readily adopted at the time, it was quickly overshadowed by the invention of the percussion cap. Manton’s weapons remain some of the most highly sought-after designs of the flintlock age and can fetch more at auction than Holland & Holland’s shotguns. His workforce included James Purdey (who went on to found Purdey’s), Thomas Boss, William Greener, and Charles Lancaster. This is a 16 bore percussion double shotgun made by Manton around the 1830s. The gun is in great shape for its age, retaining good bores and strong mechanics. With its included carry case and accessories, this will make a great addition to a fine European arms collection. After inspection by a qualified gunsmith, it may even still be suitable for more trips out in the field. Please see our photos and good luck!
