Scale: about 1:20. A model of a Wai-Pu-Ku (Chinese crooked stern junk) made entirely in wood with metal and organic material fittings. The majority of the model is made in a honey-coloured wood, with some fittings in a darker wood resembling mahogany. The hull has been carved and the model is unpainted apart from the cabin roof, which is stained black. The hull is flat-bottomed and has a flat, bluff bow which is reinforced with a substantial piece of wood. The main deck has five hatch covers intended to be removable. The single mast is positioned just forward of amidships and is rigged with a single rectangular, unbattoned sail (sail and one yard detached). The sail is made from sand-coloured cotton, with prominent dark vertical stitching running its entire length. The single cabin is positioned aft of the mast and is rectangular in plan with a curved roof. The cabin is entirely open at the front and there is a bulkhead aft of the doorway. There are two rails mounted at the aft end of the roof. The transverse-planked deck rises towards the stern and the stern itself sweeps off-centre to starboard. The counter is irregular in shape and, when viewed from behind, is much higher on the port side. The model is equipped with a steering oar, five oars with dark wood handles and a red pennant. On the main deck, there are three thole pins in the portside and three on the starboard side (two missing).

These type of vessel were used on the Kungt'an Ho river between Foochow and Kungt'an. Lacking only the built up wooden house, bow and side sweeps and being only one third the size, this type of junk is constructed along the same principles as the large salt carrying crooked stern junks. However, salt was not carried by the smaller junk, but general cargo. The advantage of the crooked stern is thought to be that, in an emergency, it permits two sweeps of different sizes with nearly the same radiusof action to operate simultaneously in a small space without fouling one another. However, this cannot apply to the small crooked stern junk, as no side sweep is carried. The explanation may lie in the fact that the crooked stern junk provides considerable additional strength to support the stern sweep, which can be 13.5m in length, 2m longer than the junks.
