This interesting little piece is part of a collection of antique Chinese iron pole cannons. There seems to be little available information on these curious antiques but I was able to locate one in the Hong Kong Military Museum. These types of cannons are typically attributed to the 17th through the 19th centuries. They come in all shapes and sizes. It would have been attached to a wooden pole and used for firing bullets or signals of sort. This piece is average size (about 26 cm in length) and weighs about 1127 grams. It has three separate barrels that are roughly 19 mm in diameter. The touch holes are open but obstructed.
