The - "duh, we have cannons" - box arrived from Brigade Games. Fresh out of the box my first impression is that they are very, very nice!
The figure is a British Marine dog handler from the Gnomes at War line at Brigade Games. (He will be kicking some pirate ass at Cold Wars) I put him there for size comparison.
There are four different sizes of cannon. The smaller one on the left has its own small carriage. The two in the middle have the same size carriage but the guns are of different size, and the large cannon on the right has a larger carriage that is sized for it.
In this shot you can see the different size cannon. I have my work cut out for me tonight!
