Comes with 2 cannons and 2 howitzers of the Napoleonic Guard as they were used between 1804 and 1815 and in the Battle of Waterloo. All guns of the Imperial French army of so-called Napoleonic Äera it was muzzleloader of bronze or cast iron fine-grained, so-called 6-pounder, with a caliber of about 90mm, more rarely to the heavier and less mobile 9- pounder of 100mm caliber , The very heavy, immovable, movable only with considerable effort on horses siege guns with calibers from 13.5 to 14.0 cm caliber, as referred 18- 24- pounder, played a role in only a few battles of the Napoleonic period. Were used much more often the lighter, kurzläufigeren 9- Pfünder- howitzers of 100 mm caliber and 12 Pfünder- howitzers, which had about a caliber of 112 mm, and about the weight of the 6-pounder cannon Langrohr- corresponded! The howitzers did not reach the maximum firing range of the cannons, were present at an arcuate curved shot ballistics behind the cover of the enemy with a more effective grenade able! The plastic gun barrels of this kit are approximately the same diameter, but 2 pieces are shorter by about half. So I'm assuming that the kit contains 2 x 9 pounder howitzers and 2 x extensive 9- pounder cannons. For this price, the kit is really equipped in great detail and plentiful!
