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 relatively small (about 16 cm in length) and weighs about 1354 grams. It has five separate barrels that are roughly 9mm in diameter. The touch holes are fused closed.
