As I've had no luck with 28mm ECW/TYW artillery during the Warlord sprue sale, I fancied a large-ish cannon from an old souvenir shop trinket. You know, the type of key chain that uses a small amount of combustible to make smoke and noise.
I added some GS details for the barrel, filling up things where required.
The carriage uses the original wheel, with the axle strengthened a bit, and pieces made from 2mm balsa wood. I went with a polished brass barrel and worn wooden colour combination.
