The English gunmakers John and Joseph ( separate businesses) Manton made some of the finest guns of the era 1805 to 1855, bridging the flintlock various pellet and tube lock stepping stones and finally percussion lock guns. They set the standard that all other quality makers strived towards. They were succeeded into the pinfire and more modern centrefire eras by several family businesses bearing the Manton name, including Manton and Company which was run by a nephew and based in India, importing guns from Britain. If It’s an English made gun it will have British proof marks and will have been a quality gun when made.
Along come the Belgians. Starting before 1900 there was a very large and lucrative trade in cheap ‘trade’ guns to primitive countries and inexpensive ‘hardware store’ guns to developing countries in south and north American like Canada. These ‘hardware store’ guns were usually marked with a hardware company name, a fanciful name or increasingly the names of defunct famous British makers and then mis spellings of some existing British and American makers, thereby avoiding legal copyright action. These guns were sold by the truckload to newly arrived pioneers who usually arrived from Europe with little but the shirts on their backs. This continued, especially in western Canada through the ‘teens, 1920’s, 30’s and up to WW2, about 1940 and the country is still flooded with them. They were very crudely made with poor material, poor heat treating, poor fitting and sloppy assembly but they were affordable and filled wagonloads of waterfowl and prairie chickens for many years. Most quickly shot loose because of shoddy manufacture, massive loads and heavy use. Their value today, if still safe to use ranges from $150 to maybe $300 for the best. They have no real collector value and almost as little as a shooter, mostly a curiosity or for display. Common faux names on these guns are Manton, J Manton, Manton and Company, W moore, William Moore, W Richards and mis spellings of Purdy, Greener, Parker and others. They are commonly referred to as “JABC”, Just Another Belgian Clunker. If it bears London or Birmingham proof marks it was once a nice gun before someone destroyed the value by chopping the barrels. If it has Belgian proof marks, the cut barrels make no difference to the minimal value.
