Very well-preserved and richly illustrated manuscript about a new type of firearm, a kind of mobile grenade launcher is introduced. The author Johann Wilhelm von Seebach (1678-1757), major general and artillery colonel of the fortification Gotha, seems to have had connections to the Dutch army, as he had already introduced his invention, according to preface, to its representatives in 1742 and 1746. The dedication in the preface is also addressed to the States-General of the Netherlands, so that the manuscript was presumably made for promotional purposes. With numerous detail illustrations- The summary at the end covers several further details, usage and advantages of the new firearm as well as its importance for armament of larger troops. - Binding somewhat rubbed, joint with small tear, upper spine end mended, else very well-preserved, almost stainless manuscript on stronger paper with lily watermark of Jean Villedary (cf.
