Copper-alloy key

Bronze key, length 15.1cm. At top a perforated lobe, now broken, for suspension, then a long flat shank hammered out at right angles to loop, decorated on one face only by border rows of in-facing latticed triangle stamps. Below this the shank is round sectioned, and at bottom is the remains of the key terminal - one side broken off and break worn so obviously done in antiquity, the other has a horizontal bar with two upright prongs or wards.
