The complexity of the Collection is reflected in the diversity of the items, from the basic division into cold steel and fire-arms to further subdivisions within these two groups. The cold steel collection contains a number of specialised collections arranged by types – for example: swords, daggers, knives, sabres, yataghans, and weapons on clubs and poles, which further subdivide into maces, clubs, battle flails, axes, halberds, glaives, partisans, spontoons and spears. This part of the collection also includes bows and arrows, and several beautiful crossbows. Apart from offensive weapons, the Collection holds a large number of defensive weapons – chest and back armour, chain-mail, shields and helmets. These collections hold various specimens, catalogued by type, workmanship, and period of production and use.
The Collection holds the oldest matchlock rifles, the most luxurious wheel-lock rifles and pistols, the finest specimens of flintlock and percussion-lock fire-arms made by the best gunsmiths in Europe, and, what is most important, in many cases by gunsmiths in Croatia: in Zagreb, Karlovac, Otocac and elsewhere. The quality and beautiful workmanship of these fire-arms made by Croatian gunsmiths can be compared with those of the best gunsmiths from Belgium, France, Italy, Germany and Austria.
