Description: | Cast copper alloy balance arm of a Medieval trebuchet coin balance (or tumbrel). Square tray attached to a rectangular sectioned arm. The arm expands slightly into an oval tail opposite the tray. There is a oval expansion in the centre of one side of this oval tail, possibly to balance the tray. One fifth of the way along the arm from the tray there is a semi circular downwards expansion with a central circular hole to hold the spindle/fulcrum. Part of the circular spindle/fulcrum remains, the rest is lost to an old break. There is no lip or stop on the tray, a feature normally encountered. It is 44.3mm long in total, the tray is 12.3mm by 12.9mm wide, the arm is 6.9mm wide and 5.1mm thick; it weighs 4.82 grams.Probably mid 12th - early 15th cent. (A. Macgregor 'Coin balances in the Ashmolean Museum', Antiquities Journal 65 (1985), 439-45).
