It’s a canon, but what sort?

Wow! What a great piece! I believe Wayne nailed it with the swivel attribution. It would appear from the pics (hard to tell, though) that the trunnions are set lower on the gun, which they would be if it were truly a 'rail' piece and allowing for steep angling downwards. Brass and bronze guns were more resistant to the salt erosion of sea air. Nice find!! I'd beg on the street for a piece like this in my meager collection-

IMA , had a googolplex of 18th century stuff they got out of Katmandu, in Nepal some years ago. This Cannon looks very similar to those short stubby 12lb cannons they had . Should have about a 5 inch bore ,. I know recycled cannon sold to Asia some times had markings covered or removed . The Bore reminds me of some guns that have a steel sleeve inserted into barrel to be safe to shoot . the bore face just looks like some bronze or other metal has been hammered over something to hide some feature . They sold for pretty good amount . I'm pretty sure that's what this Cannon is . IMA thought they where recycled Napoleonic naval guns , maybe the plate is hiding something as it is not a normal feature on guns of this kind . Small Carronade is what it is if European , but if Asian Cast .. just normal odd each one different kinda stuff .

This looks like a CARRONADE ...For some interesting reading please see https://johnsmachines.com/2016/05/11...e-vs-long-gun/

here's a small one as i suggested earlier, on a model ships boat and a similar small cannon mounted as a swivel gun on lewis and clarke's boat. i note most carronades had their trunnions much lower on the barrel, some later ones actually under the barrel, possibly to let you target objects closer to the ship/boat as carronades were very close range weapons favoured by the UK, during the american revolution and war of 1812, but one reason the US could stand off beyond carronade range and pound them into submission.

Great pics, and pointing out the lower trunions I mentioned. The Lewis and Clark expedition had one of these types mounted at the front of their boats as they went on their quest, for discouraging attacks by tribal forces.

I think everybody here has added something here . I myself didn't remember the definition of a " Carronade " , that being a Royal Navy Cast Iron Cannon type that was made by Carron Ironworks in Falkirk Scotland , 1770s to 1850s . And certainly other cannons such as this one had the same basic low velocity large bore for length equation that had the same close range effect . After looking at samples .. and I'm pretty dense, for anyone can spew out Wikipedia data .Yes as has been said most likely a swivel gun. I never thought they came so short , but I saw one example half as long as this one . I just thought it was kinda fishy that the bore obviously had a soft metal like lead hammered down on it , you can see very clearly the surface separation, hammer marks and a edge that has been leftover and into the bore itself . You might contact IMAs they have sold similar Cannon, and I'm sure they could verify if it came from them. I know that some at Least Some Asian countries even used these type for Land and fortification use . Not all Asian cannon are crude .. but is way out of the area of my knowledge base , heck of a intruder defense system.
