Scale: 1:36. A full hull model of a type of Northern Chinese junk known as a Pechili Trader (or also as a Kiangsu Trader, Shantung Trader or Shantung Five-masted junk). The model is built plank on frame and largely finished in a stain natural wood and varnished. It has five masts, none of which are stepped vertically, and is lug rigged with near-rectangular sails, supported horizontally with bamboo battens (known today as junk rigged). It is equipped with a small boat or sampan, two oars, a woven basket sea anchor, two spare sails, four anchors and three boathooks.

This model was commissioned by Lieutenant-Commander D. W. Waters RN and built in Weihaiwei by a team of craftsmen under the direction of Tung-ya. It is a particularly accurate model and is based on detailed measurements of junks made by Lt-Cdr Waters in Weihaiwei.

This type of vessel is one of the two oldest types of Chinese sea junk- the other being the Antung trader. These vessels could be up to 41 metres in length and crewed by 20 to 30 men. They have a flat bottom for inshore work, and are turret built which gives great strength. Such craft could carry up to 400 tons of cargo in numerous watertight compartments hired out to merchants. The Pechili trader is unique in the stepping of her masts, the foremast and the auxiliary mizzen being fixed to the port side and the mizzen to port of the central line (to clear the rudder post). Occasionally a large topsail and spinnaker were set in addition to the normal lugsails. The sails are supported with bamboo battens, which provide extra strength. These craft were used as ocean-going vessels to transport cargo, normally oil and large disks of compressed soya bean.
