Manufactured c. the late 1840s to early 1850s by the Peter Luneschloss firm of Solingen, Prussia, this is a very attractive example of a U.S. infantry/artillery officer's sword of the period around the Mexican-American War. Officer's swords during this period show a fairly wide range of patterns and embellishments, while also sharing many similar themes, with this example being one that is more highly embellished. It measures 36 1/4 inches overall with a 31 inch long, nearly straight blade, having a deep, wide fuller on both sides just below the spine that runs approximately half the length. The lower third of the blade is ornately finished in niter blue with etched floral motifs and panoplies of arms, with the Luneschloss "PD.L" maker's mark on the lower right side. The hilt is gilt brass, with the guard having an eagle head quillion, half clamshell shield on the right ornamented with a relief American eagle and shield, and a recurved D-shaped knuckle guard with floral motifs. The floral motifs continued onto the grips along with incised smooth pearl grip scales and ending with a highly detailed, relief eagle head pommel, which was one of the iconic themes of swords of the period. The scabbard is of gilt brass with oak leaf and other floral engraving along with fan motifs and dots. The upper locket has a suspension ring on either side for vertical suspension and the lower locket has one ring for a more vertical suspension.
