A pair of flint-lock rifles, signed by Lars Berrig Trundheim. Both pictures and inscriptions on the rifle butt, relates to Christian V's journey to Norway in 1685. Presumably a present to the king, given upon his return.
The rifles are inlaid with precious materials and thus was not used in warfare. Such ceremonial weapons were often inlaid with detailed decorations in the form of monograms or pictures of important landmarks.
The spring-lock mechanism with its simplicity and efficiency, became immensely popular in the 1660's, and quickly became the preffered choice for any respectable musketeer.
