I was having a look today at some of the Percy Tenantry Volunteers' gear that is in Alnwick castle. They have a nice 3 pounder brass cannon ...... and next to it a couple of these small three barrel cannons. I immediately thought of your 'large musket ball' .... a perfect fit I bet!
I've not yet found anything like this elsewhere on the internet, apart from some muli-barrel medieval affairs. I can imagine these being very effective fired at cavalry and infantry.
I'm not sure if the 1805 raised Artillery component of the PTV practiced at Alnmouth, but if it turns out they did, then it is highly likely your ball came out of this gun?
