This is a plastic American Civil War cannon with caisson. From BMC, cannon measures 4" long with elevating barrel. (2" figures for scale only and not included with this set) Caisson measures 5 1/2" long with hitch for horses (we have some BMC horses in our ebay store that could probably be adapted for this caisson...just drill a hole in side of horse) Cannon and caisson could work well for a variety of 19th Century battles!
