Model of a 12-Pounder Gun on a Carriage

Model of a 12-pound cannon on a truck. The 41.4 cm long barrel has a caliber of 19 mm. The cheeks of the truck, with three steps and an arched cutout at the bottom, are further apart at the back than at the front and are connected by the neck, breastwork, sole plate, front axle box, and three bolts through the cheeks. The wedge and elevation plateau are missing. The wheels are wooden; the front wheels are larger than the rear wheels; the rear wheels are placed between the cheeks under the sole plate. Scale 1:6 (presumably).
