Catalogue entry no. 494 by Max Loehr:
494 Long Hook Terminating in Dragon Heads
Whitish translucent jade with a few brown markings. A shaft, elliptical in cross-section, forms a hook at the lower end, with a short snailshell-like projection downward in the axis of the shaft. Both ends terminate in dragon heads of slightly varying design. Except for these heads, the entire surface is diagonally fluted. There are drill-holes below each of the heads and a pair of holes in the middle of the shaft. At the back of the shaft are incised a number of transverse strokes and characters. Though indistinct on account of the fluting, these characters appear to read: ta kung i ; “great work one.” Late Eastern Chou.
