I have three table top cannons with barrels of between 11 and 12". They are all section 1. It doesn't matter if they are smoothbore or rifled (except for competition purposes) as they are under 24" barrel length. Anything over 24" and with a bore up to two inch can be held on a SGC. Obviously the small ones are more dangerous in the eyes of officialdom! This little tiny one would def be section 1.
