Characteristic form and superior quality with heavy 17 1/2" slightly concave wedge section blade. Shaped dark wood hilt with silver base ferrule and grip wrapped in bands of silver wire. Wood opened face scabbard with silver mounts covered with fine silver wire work surrounding blue stones or cabechons. Uniformly excellent condition for the period. See Rediscovering the Arms and Armor of Tibet which identifies the southeast of Tibet and Assam as culturally cohesive and classifies weapons to that area rather than by modern borders. Also in that work, swords of this era are generally identified as 17th-19th century which applies to this specimen, recognizing the absence of change in swords during that period.
