Xixia Museum Tangut Commander seal 12

Western Xia "Commander" seal, with the two Tangut characters "𗥦𗖅" (Chinese shǒu lǐng 首領 "commander") in seal script on the seal face. Seal is displayed under the imprint of Seal 01. According to the museum information card this seal is dated wuchen 5th year (戊辰五年) = 5th year of the Renqing era (人慶五年) [1148], but as the seal does not correspond to the seal imprint displayed above it, this date may may actually relate to the other seal.
