The motif is similar to that on a bronze door pivot illustrated by Rawson, Chinese Bronzes, Art and Ritual, 1987,no. 30, where she states that "Many angular bronze architectural ornaments were excavated from pits at Fengxiang Xian in Shaanxi province. Like other bronzes from this western area, at the time part of the state of Qin, the bronze sections carry large, slightly rough dragon interlace". She also mentions that "others have come from the southern provinces of Jiangsu and Hubei." Compare, also, a bronze fitting with similar design, described as either from a piece of furniture or part of a door, in the Natanael Wessen Collection, illustrated by Karlgren and Wirgin, Chinese Bronzes, 1969, pl. 50
