This is my entry Dragons Sexton with a crew an limber from Bronco, I've found a few photos of Sextons in Italy I'm going to do it as an in action gun. My initial thoughts were to have it going over a Bailey bridge, that was spanning an old Italian bridge that couldn't take the weight. But I couldn't think why the number 1, wouldn't have pulled of the bridge to carry out his fire mission.
Here is a few photos of a Dragon priest I built a while ago, I used the dragon British infantry sets and moved the arms about.
