These are very useful one-piece resin castings of "Pirate Cannons" (yes, there is a tiny skull on the gun barrel) from Lewis Davis at Minimi. I cleaned up and painted them in less than 15 mins from start to finish. I have placed a 1/76-1/72 converted Thai figure next to them for scale.
These cannons will be used for the 16-17th century Siamese army (1/72) that I have just started to build. I also have Minimi's "Dragon Cannons" which I will paint up in the same way soon.
