WIP of the Reformation War-era Aludran railroad gun Kazit Zoya ("Little Zoya"), mentioned here. This 23-inch supergun is named after the lead designer's daughter, and was the cannon that breached the outer wall of Lons Fortress in Linthe and one of the battery of guns assembled to destroy the outer wall of Janek after the south-facing 12-inch L/70 anti-siege cannon Stiletto was disabled.

Did some scaling based on the barrel to get the ladders the right size, and Zoya is an absolute leviathan of a gun: the gun carriage is 29'9 tall and 201'3 long, which is actually longer than Schwerer Gustav :o
