Back to this post... checking today in my game: it seems the cart is just one of the (two? several?) standard models for renaissance industrial-trader: see screenshot below, : while my japanese (white-red) trader is the "poor" model, with mostly apple barrels and some cloth rolls, the maori (purple-teal) trader below is a bit more lavish, carryng more fabric rolls, swords, what probably is a barrel of liquor, and a hat!. Dunno if it is just randomo or if it depends in the type of trade route... but I'm afraid that's not Sinbad's cart
