Model is made entirely from brass and consists of a shank which is square in section through which is a single piece crescent-shaped arm which pivots on a large fidded bolt. The upward facing palms are flat and triangular in shape and include a flat flange drilled with a circular hole and mounted at a right angle at its widest end. Just above the arms is a pair of bow-shaped gravity shackles which swivel on a bolt. The stock is circular in section, tapering towards its ends and complete with a sphere at one end and a flattened button at the other which curves at a right angle parallel to the shank It is fidded with a metal pin on a small chain (missing) allowing it to be un-shipped and stowed flat aboard ship.
